LOW FREQUENCY SENSORS (LONG RANGE SONAR SENSOR) In real-life application, they are effectively an advanced underwater microphone that captures and interprets sound in water. Some of its primary functions are mapping the ocean floor, detecting underwater objects or impediments and tracking other oncoming moving bodies by observing the movement over water. Due to its technology such as extensive signal processing, high-frequency transmission and wide bandwidth etc… can operate beyond the long range at very fine resolution results better than other sensors which never had ever. The applications of this sensor are significant — from oceanography and navigation services etc. to defense, marine long-range repeatable science (MLongRrs) as well underwater exploration facilities application that too in the under water environment.. Range Sonar Sensor: For seeing through an underwater world sonar has been the watchword, and in murky waters or chaotic environments this innovative can take you the
