对多基地雷达系统各接收站获取的目标一维高分辨距离像进行特征提取，可得到目标散射中心在多个方向上的径向分布。根据空间矢量投影的原理，可以求出目标散射中心之间的真实位置关系，形成目标的三维像。仿真结果表明，用三维像描述目标的结构具有较好的稳定性，可作为目标识别的特征量，从而为利用高分辨距离像进行目标识别提供了新的方法。

By extracting the characteristics of range profile of each receiving station in multistatic radar system, the distributions of scattering centers in several directions are obtained. Based on the theory of projection of vector, the geometry of scattering centers can be worked out. Then the three-dimensional image can be formed. A high stability can be obtained to describe target structure by its three-dimensional image. And the three-dimensional image can be used as character of target for recognition. This paper proposes a new method for target recognition by using high resolution profile. The analysis is vatidated by simulation result.
