Abstract:

This paper presents a method to interface sound navigation and ranging(SONAR) with fire control system(FCS) and detection of targets. A submarine navigator keeps track of surrounding submarines and active targets such as torpedoes or mines and passive targets such as rocks, friend submarine or a ship, in order to have tactical information of its neighborhood. At present this is carried out manually by trained sonar operator. This task of classifying the object as either mines or rocks by training an artificial neural network using tensor flow framework, thereby giving the submarine (ship) syst

Abstract:

Sound Navigation and Ranging (Sonar) is underwater sound detection used in boats or submarines to navigate, communicate with or detect objects under the surface of water based on sound propagation. It is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves. Based on signal data obtained from sonar, this article presents a new heuristic approach inspired from black holes' phenomenon proposed by Schwarzschild, it has been applied to the classification sonar returns from two undersea targets, a metal cylinder and a similarly-sha

Abstract:

Sonar atau Sound Navigation and Ranging adalah teknik yang digunakan untuk menentukan posisi (jarak) menggunakan media gelombang suara. Sonar banyak dipakai untuk mengetahui situasi yang ada di dalam kolom air tertentu. Selain itu sonar juga berguna untuk mengukur jarak serta mencari atau mendeteksi suatu benda yang ada di bawah permukaan laut. Sonar bekerja dengan menggunakan prinsip mengirimkan gelombang suara dan akan dipantulkan kembali ketika gelombang tersebut mengenai suatu objek atau benda. Dalam Tugas Akhir ini penulis bermaksud untuk mengembangkan purwarupa peralatan pencitraan

Abstract:

Mines in the waters are just explosives that detonate upon contact with an object. The underwater submarine must foresee if it will encounter a mine or a rock. Lacking the development of the Ranging Sound Navigation approach, which utilizes particular variables to identify whether a surface or a barrier is made of a mine or rock, finding mines or rocks would have been extremely difficult. In our study, we demonstrate a technique for predicting underwater rocks and mines using SONAR waves. At 60 different angles, SONAR pings are employed to record the various frequencies of submerged objects. T

Abstract:

Underwater acoustics has been implemented mostly in the field of sound navigation and ranging (SONAR) procedures for submarine communication, the examination of maritime assets and environment surveying, target and object recognition, and measurement and study of acoustic sources in the underwater atmosphere. With the rapid development in science and technology, the advancement in sonar systems has increased, resulting in a decrement in underwater casualties. The sonar signal processing and automatic target recognition using sonar signals or imagery is itself a challenging process. Meanwhile,

Abstract:

Sonar (Sound Navigation and Ranging) system is an advanced underwater object-detecting system for navigation. The sonar system aids in detecting obstacles and the presence of enemies within a given range. The sonar system detects the targeted objects by identifying the radius and range of the targeted objects. One of the major problems that affect the application of the sonar system is the inability to detect objects due to excessive echoes and noise in the spectrum. The excessive echoes created reverberations that tend to distort the original reflected signal of the sonar system. This researc

Abstract:

Sonar is an abbreviation of (sound of ranging), which means the technique of spreading the sound for navigation and communicating or detecting other ships. Sonar can be applied to measure the distance of an object by reflecting ultrasonic waves to the object and then captured through the reciver. The ultrasonic wave is reflected by the SR04 sensor and uses Arduino Uno as a microcontroller where its distance is calculated. LCD is used to display measurement results so that it is easier to take height measurements. Arduino is a device that can be programmed and connected directly with an ultraso

Abstract:

Underwater detection is accomplished using an underwater ultrasonic sensor, sound navigation and ranging (SONAR). Stealth to avoid detection by SONAR plays a major role in modern underwater warfare. In this study, we propose a smart skin that avoids detection by SONAR via controlling the signal reflected from an unmanned underwater vehicle (UUV). The smart skin is a multilayer transducer composed of an acoustic window, a double-layer receiver, and a single-layer transmitter. It separates the incident signal from the reflected signal from outside through the time-delay separation method and can

Abstract:

Improving the operational efficiency and optimizing the design of sound navigation and ranging (sonar) systems require accurate electrical equivalent models within the operating frequency range. The power conversion system within the sonar system increases power efficiency through impedance-matching circuits. Impedance matching is used to enhance the power transmission efficiency of the sonar system. Therefore, to increase the efficiency of the sonar system, an electrical-matching circuit is employed, and this necessitates an accurate equivalent circuit for the sonar transducer within the oper
