摘要
机载雷达侦察设备通常都采用脉冲消隐技术避免载机雷达干扰,该项技术降低了脉冲截获概率。为此,提出了采用极化技术抑制载机雷达干扰的方法,该法克服了脉冲消隐技术的先天缺陷,实现了雷达和侦察接收机兼容工作,提高了脉冲截获概率。还讨论了极化参数的估计方法和滤波器实现问题,仿真证明了其有效性。
Airborne radar reconnaissance equipment usually uses pulse-blanking technique against the interference of the local radar signal. As this technique would decrease the pulse acquisition probability, a polarization method is given to suppress the local radar interference. The new method overcomes the inherent shortcoming of the pulse-blanking technique, and enables the reconnaissance equipment and radar equipment to work simultaneously, thus, the pulse acquisition probability is increased. The estimation of polarization parameters and the realization of the polarization filter are discussed, too. Simulation proves the effectiveness of the method.
