FIELD: radio engineering, communication.SUBSTANCE: apparatus for monopulse measurement of radial velocity of objects consists of two identical channels for processing probing and reflected chirp pulses, connected to first and second outputs of an electronic switch, wherein the probing chirp pulses arriving at the electronic switch and a chirp pulse reflected from a moving object are switched with the corresponding processing channel. Each processing channel consists of series-connected band-pass filter, multiplier, to one input of which chirp pulses are transmitted from the output of the band-pass filter, and to the second input of which the same pulse is transmitted, but delayed by a delay line, an integrator, a phase-locked-loop frequency control circuit, a frequency meter, wherein the output of the frequency meter of each channel is connected to the input of a comparator device, the output of which is connected to a decision device.EFFECT: enabling measurement of radial velocity of a moving object while preserving the capability to measure range to the object.2 dwg |
