提出了一种新的评价假目标红外示假效果的方法。该方法首先采用Harris算子提取**目标及其相应假目标的红外图像的特征点，然后采用Hausdorff距离计算所提取的特征点集之间的Hausdorff距离。该距离越大，说明假目标与真目标相差越大；该距离越小说明真、假目标越相似，也就是说假目标的红外示假效果越好。

A new method to evaluate effect of decoy in the infrared band is proposed. Harris operator was adopted to extract the feature points of the images of target and its decoy,and then the improved Hausdorff distance was used to measure the Hausdorff distance between the two feature points sets. The smaller the distance is,the greater the similarity is between them and the better the effect of the decoy is.
