Therefore, a new approximation model for alternating phase shift mask considering shadowing effects was proposed in this paper, and shadowing ratio was redefined. 因此本文针对交替式相移掩模(PSM),提出了一种考虑阴影效应的近似模型。

The Binary phase shift keying ( BPSK ) and Mary amplitude shift keying ( MASK ) are widely used in radar systems, their elliptic covariance do not equal zero, are noncircular signals. 二进制相移键控(BPSK)和幅度调制(MASK)等信号是雷达系统中常用的信号,这种调制信号的椭圆协方差矩阵不为零,被称为非圆信号。
