RADAR Russian patent published in 1997 - IPC

FIELD: radar equipment, in particular, radar scanning. SUBSTANCE: device has active radar channel and passive wide- band channel with compensation of side lobes of antenna. Passive channel provides possibility to find direction to signal sources in parallel to active radar channel. All information from both active and passive channels is displayed on generalized indicator. Radar has code generator, transmitter which is connected through circulator to antenna with angular position detector. In addition device has high-frequency amplifier, which is connected to circulator, balanced filter for pulse compression and threshold gate. Additional phase manipulator, clock oscillator, phase detector, all-directional antenna, second high-frequency amplifier, two detectors, comparator, N channel band-pass filters, N channel detectors, N channel comparators, N channel gates, N channel static flip-flops, threshold signal detector, two multiplexer, two counters, decoder of final code, function generator, decoder of pixel number, memory unit, 2 (L + N) pixel multiplexers, static register, shift register, digital-to-analog converter, video monitor, master oscillator, line and frame frequency dividers, five delay gates and analog-to-digital converter are introduced to accomplish the goal of invention. EFFECT: increased functional capabilities. 2 dwg
