The inherent distance ambiguity of pulse Doppler radar increases the requirement of Doppler filter group to the clutter-suppression ability.
脉沖多普勒雷达的固有距离模糊,增大了多普勒滤波器组对杂波抑制能力的要求。
In order to detect the low-speed weak target in the stationary sea clutter, the clutter-whitening processing module is proposed to replace the conventional MTI filter and Doppler filter bank.
