METHOD OF ECHO-SIGNALS SIMULATION Russian patent published in 2009 - IPC G01S7/52 G09B9/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering field and can be used in submarine's simulator. Technical result is achieved ensured by that in method based on receiving of probing signal and its conversion by means of delay circuit, in a row shifted in time "n" signals, amplification and summing up of signals values and emission of simulated echo-signal, from received "n" signals, after conversion of received probing signal, there are formed groups with casual phase and amplitude distributions correspondingly to the value of reflected signal from particular part of submarine surface. Phase displacement value of signals inside groups, phase shift of groups to each other and signal multiplication value is changed against angle of probing signal arrival.

EFFECT: increasing of reliability of emitted simulated signal.
