本文对于宽带Frost功率反转①阵列抑制干扰的能力,在小带宽的假定下进行了定性的理论研究;同时,对于反转阵列的性能与各种参数的关系,进行了仿真实验研究。所得到的结果用来设计阵列单元后面的横向滤波器;并从可变权重数的角度评价了另外一种用几个窄带处理器构成的宽带系统。然后,定性地研究了由不同方向上的干扰源引起的频率畸变。
In this paper, a qualitative theoretical study is made under the assumption of small bandwidth for the reversal of wideband Frost power inversion. (1) The ability of the array to suppress the interference is studied theoretically. At the same time, simulation experiments are carried out on the relationship between the performance of inverse array and various parameters. The results obtained are used to design the transversal filter behind the array element. Another wideband system consisting of several narrow-band processors is evaluated from the perspective of variable weight. Then, qualitatively studied the frequency distortion caused by the interference sources in different directions.
