摘　　要：推出两个干扰波束ＰＩＣ的最佳权，输出目标、干扰、噪声平均功率以及信干噪比，信干燥比改善率的表达式．分析了它们的特性以及输出信干燥比与输入信干噪比，目标和干扰波束控制方向之间的关系．给出了计算机数值计算结果，确定了两个干扰波束窄带ＰＩＣ的使用范围．In this paper expressions are derived for the weights, the average output powers of thetarget, the interferences and the noise, the output signal to interferences and noise ratio,SINR(W), and the signal to interferences and noise ratio, SINRIR(W) for the optimizedprocessor. The SINR(W) in relation to input signal to interferences and noise ratio andsteering directions of the target and the interferences is analyzed. The adaptable area of anarrowband PIC for two interference beams is determined. Some computer studies are given.
