FIELD: physics. ^ SUBSTANCE: detection is carried out by means of scanner transmitter and receiver and transponder. Scanner transmitter comprises master oscillator, modulation code generator, phase manipulator, power amplifier and transmitting antenna. Scanner receiver comprises measuring and four identical direction-finding channels. Besides, scanner incorporates correlator, multiplier, controlled delay unit, low-pass filter, extreme controller, range indicator and recorder unit. Transponder incorporates micro strip antenna, piezo crystal, electrodes, buses and reflectors. All said devices are interconnected. ^ EFFECT: expanded performances, higher validity. ^ 3 dwg |
