基于目标距离像的地面目标检测和跟踪

本文阐述了高分辨率一维距离成像的原理,提出了一种基于目标距离像的目标信号检测和跟踪方法。理论分析与模拟结果表明,通过目标距离像可以测量出目标的一部分强散射中心;强散射中心信息的综合利用,可以提高信干比并改善检测和跟踪性能。因此利用目标距离像可以较好地解决强地物杂波背景下目标信号的检测和跟踪问题。

Ground Target Detection and Tracking Based on Target Range Profiles

The principle of obtaining one dimensional high resolution range profiles (HRRP) of a target is introduced, and a method of target detection and tracking based on HRRP is presented. Theoretical analysis and simulation results show that some of the strong scattering centers of the target can be measured with HRRP. By synthetically using the information of strong scattering centers, S/J ratio can be increased and detection or tracking performance can be enhanced. The method proposed here can solve the problem of target detection and tracking under strong ground clutter backgrounds.
