FIELD: detection of microwaves and search of stolen car. SUBSTANCE: device has receiving and transmitting antennas, low-noise microwave amplifier, amplitude microwave modulator, microwave switch with electronic control, amplitude detector, hue signal amplifier, synchronous detector and recording unit. Receiving antenna is connected to serial circuit of low-noise microwave amplifier, amplitude microwave modulator, microwave switch, which first microwave output is connected to transmitting antenna and which second microwave output is connected to one input of synchronous detector through serial circuit of amplitude detector and hue signal amplifier. Another input of synchronous detector is connected to amplitude microwave modulator and hue signal generator. Output of synchronous detector is connected to recording unit. EFFECT: increased functional capabilities. 3 dwg
