Abstract

Dethedetection of hulls requires the implementation of a built-in or autonomous provides a full range of functionalities for the detection and classification of transmitted sonar signals, generation of imitative signal with spatial parameters, analogous to those reflected by the seabed, and its radiation. This helps to model the shape, the sonar shadow and the reflective surface of the bottom mine in order to mask it by generating a packet simulating chaotic impulse disturbances with parameters corresponding to those of possible reflections from fictitious bottom objects and by re-emitting the received and additionally modeled hydro acoustic pulses with a calculated time lag to
achieve the desired result
