摘要: 本文聽述及的脈沖多普勒(PD)雷達(dá)信號處理系統(tǒng),主要由速度跟蹤環(huán)和數(shù)字信號處理輔助通道組成。該系統(tǒng)綜合運(yùn)用了多項(xiàng)信號處理技術(shù),成功地解決了在低信噪比條件下的信號檢測和跟蹤、干擾識別和對抗等技術(shù)問題。文中闡述了設(shè)計(jì)思想,交給出了部分仿真和測試結(jié)果。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.
