Abstract

The invention relates to vehicle automation and can be used on all modes of transport for identifying moving objects. The purpose of the invention is to increase credibility. In the floor unit 1, the signals from the output of the microwave generator 2 through the amplitude modulator 3 and the circulator 4 arrive at the input to the transmitting / receiving antenna 5 and are radiated into space. When a pulsed high-frequency signal from the output of frequency generator 6 in modulator 3 arrives at the second input of the amplitude modulator 3, the pulse amplitude modulation of the microwave oscillations is performed. When the detection unit 16 is located above the microwave radiation antenna 5, the receiving-transmitting antenna 17 of the detection unit 16 is received. Using the converter 18, the microwave signals are converted and a high-frequency pulse is extracted. The resonators 19 pass these signals to the switch 20. Using the contacts of the switch 20, certain delay lines 21 are connected. The delayed pulses through the resonators 19 are fed back to the converter 18, where the microwave oscillations are modulated. Using the antenna 17, the modulated microwave signals are radiated towards the floor block 1. 1 sludge.

The output of the microwave generator 2 through the amplitude modulator 3 and the circulator 4 is fed to the input of the transceiver antenna 5 and radiated into space. When a pulse high-frequency signal arrives at the second input of the amplitude modulator 3 from the code of the frequency generator 6 in the modulator 3, the pulse amplitude modulation of the microwave oscillations is performed. When the identification unit 16 is located above the antenna 5 of the microwave radiation, the transmit-receive antenna 17 of the block 16 is received.

Radiator 18 converts microwave signals and extracts pulsed high-frequency oscillations. The resonators 19 pass these signals to the switch 20. Using the contacts of the switch 20, certain delay lines 21 are connected. The delayed pulses through the resonators 19 are fed back to the converter 18, where the microwave oscillations are modulated. Using an antenna 17, the modulated microwave signals are radiated towards the floor-standing unit 1. 1 Il.

through the switch 20 and the delay lines 21 are interconnected.

The device works as follows.

In the floor unit 2, the signals from the output of the microwave generator 2 through the amplitude modulator 3 and the circulator 4 arrive at the input of the transmitting / receiving antenna 5 and are radiated into space. When a pulsed high-frequency signal from the output of a frequency generator 6 in modulator 3 arrives at the second input of the amplitude modulator 3, the pulse amplitude modulation of the microwave oscillations is performed.

When the identification unit 16 is located above the transceiver antenna 5, the microwave oscillation radiation is received by the transceiver antenna 17 of the recognition unit 16. The converter 18 transforms (detects) the microwave signals and extracts the high-frequency pulse.

Resonators 19 pass these signals to switch 20. Certain delay lines 21 are connected through the contacts of switch 20. The delay times in lines 21 are different and differ among themselves at least for a time equal to the pulse duration of the high-frequency signal from the output of the frequency generator.

The delayed pulse signals through the resonators 19 are fed back to the converter 18, where they modulate the microwave oscillations. Using the transmitting / receiving antenna 17 of the identification block 16, the modulated microwave signals are radiated

in the direction of the floor unit 1, in the floor unit 1, the signals received by the transceiver antenna 5 through the circulator 4 arrive at the input of the unit 7, the second input of the prohibition unit 7 receives signals from the output of the synchronizer 15, which for the time of the signals emit close the first mixer 8, The reflected signals arrive at the first input of the mixer 8, and the second input of the mixer 8 receives a signal from the second output of the microwave generator 2.

The frequency-converted signal from the output of the mixer 8 enters the receiver 9, where it is amplified to a predetermined level and is fed to the input of the detector 10. From the detector output, 10, the signals arrive at the controlled accumulator 11. After accumulating for several periods, signals go through the threshold element 12 the decoder 13. The decoded signals through the block 14 arrive to the consumer.
