DEVICE FOR DETECTING OBJECTS EMITTING ACOUSTIC SIGNALS

摘要

FIELD: radio engineering, communication.SUBSTANCE: method is carried out by introducing a second loop for transmitting optical signals at a different wavelength and a series of following units: (2N+3)-th light guide, third photodetector, second pulse generator, second optical radiation source, (2N+4)-th light guide.EFFECT: high accuracy of locating and identifying the type of an object by evaluating the spectral composition of the acoustic noise and motion parameters thereof.1 dwg
