title: DISCOVERY OF OBJECTS IN AQUATIC ENVIRONMENTS
abstract: Searching, detecting and tracking underwater objects is an extremely important task, which is solved with the help of various hydroacoustic devices. Depending on their mode of operation, they are divided into two main groups - active and passive. Active hydroacoustic devices work by emitting a sound signal with certain parameters in the surrounding space and receiving echo signals reflected from underwater objects. With passive devices, we receive the sounds and noises characteristic of a given
