METHOD FOR DETECTING UNDERWATER OBJECTS AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G01S15/00 G01S3/80 

FIELD: hydro-acoustics, possible use in hydro-locating technologies for detecting underwater objects like submarines and small objects like mines and underwater swimmers.

SUBSTANCE: method includes determining, in the moment of temporary position of expanding spatial angles wave front, tracking belonging to acoustic beam (bearings) for each reflective element, positioned in wave packet of reflected signal (in space between frontal and back fronts of signal pulse, and limited body angle of direction characteristic of receiving antenna. Spatial receipt on basis of spatial-phase and spatial-correlative processing of reflected signal provides for detecting difference between spatial positions of reflecting objects within received signal wave front, which provides more information for object detection and, due to that, principally distinguishes the method from commonplace amplitude-temporal signals processing technology.

EFFECT: limited reverberation effect due to organization of spatial processing of signal.
