UWB SAR works usually in low Signal-to-Clutter Ratio (SCR) conditions in order to detect targets hidden in forest or buried in ground.
超宽带合成孔径雷达（UWB SAR）为了探测隐藏在树林中或埋于地下的目标，通常工作在低信杂比的环境中。
The results show that when the millimeter wave radar has the short-distance detection, signal-to-clutter ratio is more than signal-to-noise ratio. So rainfall is an important impact factor.
结果表明：在毫米波雷达近距离探测时，信杂比大于信噪比，雨杂波是重要的影响因素。
Simulating experimental results shown the algorithm is especially suited for surveillance system of low frame rate and can detect the point targets with signal to clutter ratio equal to 2.
模拟实验表明，该算法特别适用于低帧率的红外警戒系统，可检测信杂比为2的点目标。

By comparing the effect between pre-and post clutter reduction, the clutter reduction method increases the signal-to-noise ratio (SNR) of the radar images and improves the detection performance.
从比较结果可以看出，采用该方法抑制这类杂波的效果较明显，通过杂波抑制可以获得更好的图像质量。
