摘要
FIELD: physics.;SUBSTANCE: device has two receiving channels, integral and differential, consisting of an input filter, a high frequency amplifier, a mixer whose second input is connected to a heterodyne, an intermediate frequency log amplifier and a limiter, as well as a subtractor circuit, a phase detector, where the output of the limiter of the integral channel is connected to series-connected intermediate frequency filter, detector, video amplifier, threshold device and switch, where the number of such connections is defined by the number of code frequencies of the frequency-time coded radio-pulse response signal, and signals from threshold devices is fed to the inputs of switches, control inputs of which are connected to the output of the subtractor circuit.;EFFECT: obtaining information when there are several carrier-frequencies and the information is embedded in the sequence order of frequencies, their values and pulse delay of frequency-time coded response signals relative the first signal.;2 dwg
