FIELD: physics.
SUBSTANCE: distance to a target is determined using a multichannel storage device at the output of a Doppler filter system, based on measurement of time delay of response at the output of a matched filter for a specially generated composite signal, wherein the duration of said response is substantially (e.g. tens or hundreds of times) shorter than the duration of the tonal signal response. The composite signal is generated using the tonal signal response of the echo signal at the output of the Doppler channel in which said echo signal is detected, and the modulating function of the composite signal.
EFFECT: higher accuracy of determining distance to a target.
