FIELD: radar engineering.
SUBSTANCE: proposed noise-immune radar system that incorporates provision for maintaining its serviceability in complex electromagnetic situations and intensive background returns from passive noise, local objects, and meteorological formations, as well as for measuring radial speed of target by Doppler frequency shift has tunable microwave oscillator, two gating stages, two gate-pulse generators, synchronizer, τ pulse length delay line, adder, transmitter, transmit-receive switch, transceiving antenna, pulse modulator, high-frequency amplifier, two band filters, two mixers, two intermediate-frequency amplifiers, three phase detectors, two switching circuits, processor, and repetition rate delay line.
EFFECT: enhanced immunity to active noise and facilitated measurement of target radial speed.
