Arrangement for radar signal processing in a Pulse-Doppler radar

摘要

The arrangement for radar signal processing in a Pulse-Doppler radar contains a Doppler filter bank comprising a plurality of Doppler filters, at least some Doppler filters having variably adjustable filter weightings. A clutter detector identifies the intensity of the fixed clutter. According to the identified clutter intensity, the filter weightings of at least the moving-target filters adjacent to the clutter Doppler frequency spectrum are adjusted in such a way that the passbands of these moving-target filters are shifted further in the direction of the clutter spectrum in the case of low-intensity clutter than in the case of high-intensity clutter.
