用傅里叶变换对含有噪声干扰的试验数据进行滤波，通常难以确定奇异点在空间的位置及分布情况。
It is difficult to confirm the position and distribution of singularities in space generally when the test data with noise disturbance is filtered by Fourier transform.
首先分析了无源雷达成像系统的目标回波形式，得到了目标散射分布函数和雷达接收信号之间的傅里叶变换对关系；
Relationship between the target scattering function and the echo signal is deduced to hold as a Fourier transform pair by analyzing the texture of echo signal for a passive radar imaging system;
