摘　　要：本文主要以模拟波束合成和数字波束合成的划分为变量,分析了子阵级数字化相控阵的接收灵敏度及动态范围特性,同时提出了能够将经典接收链路性能计算扩展到接收阵列使用的方法。最终实例分析了数字化程度对于接收系统性能的影响。Receive sensitivity and dynamic range performance of the subarray-level digital receiver array has been discussed in this paper,with the division between analog and digital combination as the variable.Also,to accommodate the array application,the classic cascade method is modified.An example illustrates the influence of the level of digitization on the receiving performance.
