Abstract This paper discribes a signal processing system in a Pulse Doppler (PD) radar. It mainly consists of a velocity tracking loop and a digital signal processing auxiliary channel. With many signal processing techniques, the system sucess-fully resolves the signal detection and tracking at low SNR and the interference identification and rejection. The idea of system design is introduced in details. Finally, some simulation and expreimental results are presented.
