FIELD: radio engineering, communication.
SUBSTANCE: method is based on being used as a probing signal of a periodic sequence of radio pulses with linear frequency modulation (LFM) and characterizes intermittent change in the sign of the frequency deviation, wherein the received signal is processed by a digital generator of quadrature components, then by linear filters consistent with a single LFM pulse with positive and negative frequency deviation, followed by intermittent compensation of enveloping responses of the matched filters, and based on the measurement of the time position of the minimum and maximum difference signal, selection of moving targets and estimation of these parameters are performed.
EFFECT: possibility of simultaneous selection of moving targets with measurement of the range, radial velocity and direction of motion.
