Abstract

In the following research, we derive a detector which is based on sequential probability ratio test (SPRT) and it uses Energy Detector (ED) which is followed by Cyclostationary Feature Detector (CFD). ED is a blind sensing technique and it is easy to implement while conceptually simple. However, it is highly affected by interference and noise uncertainties. Therefore, CFD is applied for fine sensing as research has shown that Cyclostationary Feature Detector is more suitable than the energy detection when noise uncertainties are unknown. Our method is novel in trying to derive a sequential Energy Detector and combine it with Cyclostationary Feature Detector for low SNR region where average sample number (ASN) as a random variable may take very high value to achieve a desired performance level for sequential Energy Detector. For this sequential Energy Detector is terminated after it reaches certain cut-off sample number, making it truncated sequential Energy Detector.

Abstract

The radar air surveillance system consists of 4 main parts, there are antenna, RF front-end, radar signal processing, and radar data processing. Radar signal processing starts from the baseband to IF section. The radar waveform consists of two types of signal, there are continuous wave (CW) radar, and pulse compression radar [1]. Range resolution for a given radar can be significantly improved by using very short pulses. Pulse compression allows us to achieve the average transmitted power of a relatively long pulse, while obtaining the range resolution corresponding to a short pulse. Pulse compression have compression gain. With the same power, pulse compression radar can transmit signal further than CW radar. In the modern radar, waveform is implemented in digital platform. With digital platform, the radar waveform can optimize without develop the new hardware platform. Field Programmable Gate Array (FPGA) is the best platform to implemented radar signal processing, because FPGA have ability to work in high speed data rate and parallel processing. In this research, we design radar signal processing from baseband to IF using Xilinx ML-605 Virtex-6 platform which combined with FMC-150 high speed ADC/DAC.

Abstract

This research is about an effort to increase the robustness of the Minimum Variance Distortionless Response (MVDR) algorithm to noise by using a chirp signal for direction of arrival estimation (DoA). DoA is a part of radar capability to estimate the angle of arrival on the object under observation. The conventional MVDR as proposed by J. Capon, was designed to work with the monochromatic sinusoidal signal. Even though the conventional MVDR work on low SNR up to 0 dB, however, the conventional method does not work well if chirp signal is used instead of monochromatic sinusoidal signal. The usage of MVDR chirp signal is essential in the case of a very low SNR environment such as in long distance object detection, which is typically more than 10 km. The problem to be solved in this research is how to modify the MVDR algorithm so that it can work well on chirp signal. In this research we offer a modified MVDR algorithm by adding the matched filter and the phase detector components before the MVDR algorithm is applied. Matched filter is responsible for the timing of the chirp signal detection, and the phase detector is to estimate the time delay estimation of each chirp signal from each antenna with a reference signal, which correspond to the phases. Based on the phase estimation, sinusoidal signal is generated and fed to the MVDR algorithm. On the technical aspect, the chirp signal is sent intermittently with a duration of 100 ?s and repeated in time interval of 1 ms. The antenna sensor using an array of Uniform Linear Array (ULA) which consist of N-elements. Computer simulation shows that the modified MVDR using the chirp signal improve the robustness of the algorithm up to -30 dB, while on the other hand the classical MVDR works only up to 0 dB SNR. -30 dB of SNR is the minimum requirement of 3D Radar existing.

Abstract

Sleep apnea is a sleep disorder that has a relation with respiratory system during sleep.One of the sleep apnea characteristic is suddenly stop breathing during sleep. Peoplehave the dierent of respiratory rate (RR) which is affected by sleep positions andbody mass index (BMI).There are four sleep positions aecting the respiratory rate(RR). Polysomnography (PSG) is conventionally used to analysis the sleep apnea. Thistechnique requires body contact that might be uncomfortable for the patient. In thisstudy, the Xethru X4M200 radar sensor is proposed as non-contact tool to detect the RRby implementing the Doppler effect. Furthermore, the relation between RR with the sleepposition and the BMI are discused. For that purpose, 20 participants (10 males and 10females) with dierent BMIs and sleep positions are examined by monitoring their chestmovement. This method is able to detect the indication of bradypnoea or tachypnoea.Futher systematic study and more participants are required to confirm our results andprovide better non-contact technique for RR measurement.

Abstract

In general, Radar or Radio Detection and Ranging is an electromagnetic wave system that is useful to measure distance and answer and make maps of surrounding objects. Radar has an advantage compared to other navigation tools, which is that radar does not require a transmitter station as a transmitter. Radar has an electronic wave emission principle that emits short radio wave pulses emitted in a narrow beam by a directional antenna. In this study, a multi-object radar detection simulation was carried out using Dopler processing both MTI and PDP, which later on the radar will detect related objects. Multi-object here is a condition that is achieved when a navigation radar detects more than one object. The result of this research is a multi-object detection process using the MTI and PDP methods and the matched-filter obtained from the predetermined data. So Doppler processing aims to mitigate the clutter signal to improve the detection performance of moving targets even though there is a dominance of signals originating from stationary clutter.

Abstract

An electronically steerable passive array radiator (ESPAR) antenna can be used on a beamspace (BS)-multiple input multiple output (MIMO) system to reduce the device complexity. An ESPAR antenna has beamforming ability with single RF chain. However, antenna structure and channel conditions affect the number of orthogonal basis pattern which generated using Gram-Schmidt method. Based on this problem, reactance value at each parasitic element need to be optimized to form radiation pattern that required by the BS-MIMO. In this research, Genetic Algorithm (GA) is used to optimize reactance value which represented by the correlation between the desired and achieved radiation pattern, in different number of elements and different channel condition. GA is selected because this problem can be modeled as chromosome and several individual. Furthermore, the result shows in channel-ignorant and channel-aware, antenna with seven elements has a correlation in median value of 99.46% and 90.58%, respectively. Antena electronically steerable passive array radiator (ESPAR) dapat digunakan dalam sistem beamspace (BS)-multiple input multiple output (MIMO) dalam mengatasi kompleksitas perangkat. Antena ESPAR memiliki kemampuan untuk membentuk pola radiasi pada arah tertentu dengan menggunakan terminal tunggal, namun struktur antena dan kondisi kanal mempengaruhi pola dasar ortogonal yang dihasilkan melalui metode Gram Schmidt. Berdasarkan permasalahan tersebut, nilai reaktansi pada setiap elemen parasit perlu dioptimasi sehingga dapat menghasilkan pola radiasi yang dibutuhkan oleh sistem BS-MIMO. Pada penelitian ini, Algoritma Genetika digunakan untuk mengoptimasi nilai reaktansi yang direpresentasikan melalui korelasi antara pola radiasi yang dibutuhkan dengan pola radiasi yang dihasilkan, dalam jumlah elemen yang berbeda dan kondisi kanal yang berbeda. AG dipilih karena permasalahan ini dapat dimodelkan sebagai kromosom dan beberapa individual. Hasil analisis pada kondisi channel-ignorant dan channel-aware menunjukkan bahwa antena dengan tujuh elemen memiliki korelasi nilai median sebesar 99,46% dan 90,58%.

Abstract

Fish farming is common in Indonesia. The farmers usually use ponds with a large size for cultivation which have constraints on feeding due to their size. An automatic feed system with An Unmanned Surface Vehicle (USV) can be the solution to overcome this problem. The USV moves to the predetermined position and direction using GPS and compass. When it has arrived at that point this USV feeds the fishes according to the predetermined amount. In this study, the Pixhawk is used to control the USV to accomplish the given mission. It uses mission planner software for determination of the waypoint points, the calibration of components, and the control of PID. The Pixhawk also serves as a ground control station (GCS) for monitoring the motion and position of the USV using radio communication of 433MHz telemetry connected to the GCS and computer. The fish feeding system uses a load cell sensor to measure the weight of the feed to be thrown and two servo motors as a feed production system. Both sensor and servo motors are controlled by an Arduino UNO. The feed tank has a maximum capacity of 7.5 liters with 0.41 cm per kilogram buoyant force of the USV. The test was carried out on a pool of 10 × 10 m by placing 4 Waypoints. The USV has an average speed of 0.65 m/s and reaches a total distance of 55.5 m in 88 seconds. Before releasing to the pond, the feed weight is measured using a load cell sensor which has an accuracy of 98.99%. The difference between the set point and the feed released by the USV is very close, where the average error value is about 4.98%. The error value becomes smaller when more weight is set.

Abstract

Di Taman Edukasi di Desa Wangisagara, Kecamatan Majalaya, Kabupaten Bandung, Provinsi Jawa Barat, kualitas air yang digunakan masih sangat buruk dikarenakan sumber air yang kurang mempuni. Situasi ini tidak sesuai dengan target SGD yang memastikan semua orang berhak dapat mengakses air bersih. Kondisi air yang demikian dapan mengganggu kenyamanan pengunjung untuk menggunakan fasilitas yang ada. Pada kegiatan pengabdian masyarakat yang difasilitasi CSL 2022, akan direalisasikan sistem filter air untuk memperbaiki kualitas air di taman tersebut. Disekitar sistem filter air juga dipasang papan edukasi yang menginformasikan tentang indicator air bersih, cara pengujiannya, proses filterisasi air, dan bagaimana merawat filter air. Sehingga papan tersebut dapat juga menjadi sumber edukasi bukan hanya pengurus taman namun juga pengunjung. Air yang dihasilkan mengalami perbaikan kualitas dari sebelumnya. Dari pengelolah taman merasa sangat terbantu dengan adanya sistem filter air ini. Kedepannya sumber air akan diganti dengan air tanah sehingga dapat menghasilkan air yang lebih baik.

Abstract

Seiring usia, fleksibilitas mata mengalami penurunan, begitpula dengan ketebalan dan kejernihan mata. Lensa terdiri dari air dan serat protein. Dengan bertambahnya usia, komposisi mata mengalami perubahan dan struktur serat protein mengalami penurunan. Beberapa serat protein akan menggumpal dan menyebabkan noda pada lensa mata. Banyak kasus mata katarak berkembang secara lambat dan tidak mengganggu pandangan mata Anda pada awalnya. Katarak biasanya tumbuh secara perlahan dan tidak menyebabkan rasa sakit. Pada tahap awal kondisi ini hanya akan mempengaruhi sebagian kecil bagian dari lensa mata anda dan mungkin saja tidak akan mempengaruhi pandangan. Saat katarak tumbuh lebih besar maka noda putih akan mulai menutupi lensa mata dan mengganggu masuknya cahaya ke mata. Awalnya cahaya yang terang dan kacamata dapat membantu penglihatan. Ketika hal ini sangat mengganggu aktivitas keseharian, maka operasi merupakan prosedur yang dibiutuhkan. Pada tugas akhir ini akan menggunakan metode Transformasi Hough. Metode tersebut akan mengekstrasi ciri pada citra untuk mendapatkan informasi yang dibutuhkan dalam pengujian. Kemudian menggunakan K-Nearest Neighbor sebagai pengklasifikasi citra dengan parameter uji titik pusat dan skala keabuan. Akurasi yang dihasilkan adalah sebesar 85,18%. Hal ini menujukkan bahwa transformasi hough dapat membantu proses segmentasi citra untuk pendeteksian mata katarak.Kata kunci : Hough Transform, k-nearest neighbor, catarct, circle detection.
