| 摘 要： | 研究了一种在较强杂波背景下雷达二维目标图像的获取方法，该方法基于现代雷达系统的步进频率方式实现的距离高分辨率技术，通过似然比检验准则，获得目标各散射中心的空间相关信息，形成目标的二维图像。并结合米格29战机目标模型验证可行性。该方法算法简便，实时快捷，抑制杂波能力强，是高分辨率雷达在杂波背景中进行目标识别的一种可行的方法。

| Abstract: | A method for high resolution radars to construct two-dimensional images of targets in clutter background is proposed. It gathers pertinent space information of scattered center and constructs two-dimensional images of targets using high range resolution techniques achieved by the stepped frequency of modern radars and the likelihood ratio detection criterion. Its feasibility is tested and verified by an example of imaging for a Mig-29 fighter plane model. Owing to its simple algorithm, good real-time property and strong ability to suppress clutter, the method is effective in helping high resolution radars to identify targets in high-clutter background. |
