| 摘 要： | 雷达采用宽频带信号后,从目标接收到的不再是“点冶回波,而是沿距离分布开的高分辨距离像。目标高分辨距离像包含一定的目标信息,如目标的长度、几何结构等,为雷达目标识别提供了较好的基础。基于长度是代表目标固有的特征信息之一,文中提出一种基于高分辨距离像的飞机目标长度提取方法,并经外场实验验证了该方法的有效性

| Abstract: | When wideband radar signal is used, the received target is no longer a point echo, but a high resolution range profile along the distance. The target high resolution range profile contains some target information, such as target length, geometric structure and so on, which provides a good basis for target recognition. Length is the inherent feature information of target. Therefore,this paper proposes a method of aircraft target length extraction based on high resolution range profile, and the effectiveness of this method is verified by field experiments |
