METHOD REVIEW pulse-Doppler RADAR targets at the background clutter

摘要

Method Overview pulse-Doppler radar targets against a background of clutter, comprising the review space by forming and directional radiation in each angular resolution element search space of a coherent pulse train of probing parcels hyperbolic wobble repetition period and the duration of the pulses and their total number, satisfying the conditions of admissibility frequency separation of the received echo signals on a linearly frequency modulated frequency partsialy and sufficiency but-speed selectivity radar to detect targets against a background of clutter and unambiguous speed positioning detected targets coaxial directional reception in pauses probing parcels radar echoes purposes and interference reflections with subsequent time-frequency treatment by blanking the received echo signals on the radiation time probing parcels, their frequency division on a linearly frequency-modulated partsialy, frequency demodulation linearly frequency-modulated partsialov, frequency rezhek tion of interfering reflections, antijamming weighting processing, multichannel spectrally a filter processing otrezhektirovannyh linearly frequency-modulated partsialov and selectively summing the spectrally a filter processing signals linearly frequency-modulated partsialov agreed on frequency and time shifts of echoes with individual bins exploratory space, and thresholding selectively summing the signals, characterized in that on completion of each cycle of the blanking
