| 摘 要： | 讨论了马氏距离的性质,利用目标的一维距离像,提出了一种雷达目标识别方法.对雷达回波进行快速傅立叶变换,得到目标的一维距离像,计算其马氏距离,得到目标的稳定特征向量,根据相关算法进行目标识别.3种不同类型飞机回波的实测数据的识别结果,表明该方法是切实可行的.

| Abstract: | The properties of Mahalanobis range were discussed in this paper. A Recognition method of radar target was proposed using range profile. First, the range profile was obtained by performing FFT. Secondly, the Mahalanobis range of range profile was computed. Then, the targets were recognized by covariance method. The experiments of identification using the practically sampled data of three kinds of aircraft targets were performed, and demonstrated that the method was effective. |
