ACOUSTIC RADAR Russian patent published in 2009 - IPC G01S15/02 

FIELD: radio engineering.

SUBSTANCE: invention may be used for determination of removal of acoustic source (AS) using acoustic radar (AR), its bearing and topographic coordinates (TC) of this acoustic source. Acoustic radar includes two linear patterns (LP) including twenty sonic detectors (SD) each, three signal processing paths (SPP), computing machine, chain of generation of selection pulse (CGSP) and chain of generation of blocking pulse (CGBP). Each signal processing path consists of signal extractor, voltage adder (VA), special amplitude detector, analog-to-digital converter (ADC) and register connected to it in series which is connected to computing machine. Signal extractor consists of twenty selective amplifiers, twenty coincidence circuits and twenty electronic switches. Chain of generation of selection pulse includes in-series connected front sonic detector, Schmitt trigger and univibrator. Chain of generation of blocking pulse includes in-series connected rear sonic detector, Schmitt trigger and univibrator. Also control system of directional characteristic is added which consists of two micro-converters, resistance-capacitance (RC) differentiator and diode, this system allows to connect outputs of selective amplifiers with inputs of voltage adder determined by program at a given time.

EFFECT: improvement of interference protection of acoustic radar, obtainment of topographic coordinates of acoustic source.
