分析了现代雷达截获系统方位截获的特点,由于恒差比幅测向具有测向精度和截获概率高以及信号处理简单的特点,在雷达截获接收机中得到广泛应用。研究了电扫描恒差比幅测向原理,独立推导了两点源电子攻击情况下恒差比幅测向的误差公式,并对其进行了讨论,该误差公式可作为对雷达截获系统进行空域电子攻击的理论根据。

The azimuth interception characteristics of modern radar interception system are analyzed.Because the characteristics of constant difference amplitude comparison direction measurement(CDAC) are that direction measurement precision and interception probability are high,and signal processing is simple.CDAC is almost adapted to radar interception receivers.The principle of electronic scan CDAC is studied.Under the condition of two point source electronic attack,the error formula of constant different amplitude comparison direction measurement is derived independently and discussed.The error formula is the theory based on electronics attack to radar intercepion system in space field.
