飞机自动目标识别通常假定在高信杂比情况下，不考虑杂波对识别性能的影响，而实际中可能包含比较强的杂波。对宽带雷达，相邻回波间会出现越距离单元走动现象，传统杂波抑制方法不适用。针对这一情况，提出了一种适合于宽带目标识别雷达的杂波抑制方法。仿真结果表明，该方法在低信杂比情况下仍可保持较好的识别性能。

The high input SCR is generally assumed in the airplane target recognition, so the influence of clutter on the classification performance is not taken into consideration, but the measured data could contain vast of clutter in practice. In this paper a new method of clutter suppression is proposed in wideband target recognition radar. Experimental results on simulated data prove that our method can keep the good performance of recognition despite the low input SCR.
