摘　　要：脉冲压缩(PC)雷达是典型的低截获概率(LPI)雷达,基于传统的雷达对抗侦察接收机与传统的检测手段很难有效截获。长期侦察表明:目前外军雷达信号形式多为脉压信号,这对我军现役的雷达对抗侦察接收机提出了严峻的挑战。数字接收机相对传统的模拟接收机有着突出的优势,基于数字接收机对PC雷达信号进行检测是根据PC雷达信号特点,充分发掘数字接收机优势的新的检测方法,有着现实的实际意义,值得深入研究。Pulse compression radar is a kind of typical low probability of intercept （LPI） radar. It＇s very difficult to intercept based on traditional radar electronic warfare reconnaissance receivers and traditional detection ways. Long-term surveillance shows that PC radar is widely used in other countries and area, and this puts forward severe challenge to our active radar electronic warfare reconnaissance receivers. Digital receiver is superior to traditional analog receiver. PC radar signals detection based upon digital receivers is a new interception technology, which takes advantage of the characteristic of PC radar signals and the potential of digital receives. It has realistic significance and is worth lucubrating.
