METHOD OF TARGET RANGE AND RADIAL SPEED IN RADAR STATION WITH CONTINUOUS RADIATION DETERMINATION AND ITS REALIZING DEVICE Russian patent published in 2017 - IPC G01S13/42 

FIELD: measuring equipment.

SUBSTANCE: subject matter of the method resides in the reflected signal reception, its demodulation, in the demodulated beat signal memorization during the probing signal modulation period, in the determination of the frequency change rate of the linear frequency modulation (LFM) and in the target radial speed calculation by dint of the linear frequency modulation attended by the reference signal generation, in the demodulation of the memorized signal and in the range on target determination on the memorized signal frequency basis. The device for the method realisation comprises the frequency modulator, the high-frequency generator, the transmitting antenna, and also the receiving antenna, the first signals multiplier, the low-frequency amplifier, the frequency change rate meter of the signal LFM, the radial speed estimator, the reference signal conditioner, the second signal multiplier, the frequency analyzer and the range computer, and also the storage device and the timing device. The enumerated devices are linked to each other in a specific way.

EFFECT: extending detection range and accuracy increase in ranging and radial speed of the high-speed targets with the radar stealth.
