RADAR WITH LINEARLY FREQUENCY-MODULATED PROBING SIGNAL Russian patent published in 1996 - IPC

FIELD: radar systems for locating objects and measuring their coordinates and parameters. SUBSTANCE: radar has transmitting device built up of carrier-frequency generator, two mixers, linearly frequency-modulated signal generator, transmitting antenna, frequency-shift oscillator, modulator, TR switch, receiving device that has receiving antenna, two band filters, mixer, polling unit, n correlating-filtering matrix channels, two memory and averaging units, subtracter, display with sweep unit, n channel modulators, strobe generator, frequency-guiding unit, frequency synthesizer. Each of n channels of correlating-filtering matrices has selective frequency mixer, band filter, rejection filter, mixer, n parallel-connected filters, polling unit, n parallel-connected filters. EFFECT: provision for locating slow-moving objects, selecting each moving object in group, suppressing echo signals from any range and passive noise signals. 4 dwg
