摘要
分析了传统二端口干涉仪抑制对消杂波原理,对其对消权值进行了自适应处理,使其不依赖于惯导设备提供的载机速度信息,并给出了该方法应用于机载相控阵雷达的具体方法。通过计算机仿真实验验证了该方法的有效性,并体现了其具有一定的空时二维滤波能力,是一种简化的空时自适应处理器。该方法结构简单,运算方便,在实际工程应用中有重要的参考价值。
The principle of traditional two-port clutter cancellation interferometer is analyzed. The cancellation weight value is processed adaptively so as to reduce its dependence on the carrier velocity information provided by INS. A specific method of application to airborne phased array radar is proposed. Computer simulation results show the validity of the method which embodies the ability of two dimensional space-time filter. Actually the method is a simplified version of space-time adaptive processing and has great reference value for engineering practice.
