FIELD: the invention refers to radar technique particularly to radiolocation systems for determination of the sign of the direction of the movement of a target. ^ SUBSTANCE: the arrangement for determination of the direction of the sign of the movement of a target has a receiving-transmitting antenna, a switch of receiving-transmitting, the first mixer, an amplifier of an intermediate frequency, a detector, a driving oscillator, a power amplifier, an impulse modulator, the second mixer, a generator of an intermediate frequency and an indicator. It has additionally sequentially connected a generator of modulation of an intermediate frequency and a modulator of an intermediate frequency whose second input is connected with the second output of the generator of an intermediate frequency and the output is connected to the second input of the detector, a filter of Doppler frequencies whose input is connected with the output of the detector, a frequency demodulator, a determinant of time changing of the frequency of the signal of the target and a correlator of changing of the frequency of the signal of the target, whose second input is connected with the output of the generator of modulation of a intermediate frequency and the output is connected with the indicator. ^ EFFECT: allows to secure increase in the speed of operation and accuracy in determination of the sign of the direction of the movement of the target. ^ 3 dwg |
