高分辨力雷达地面运动目标信号特征分析

文章提出了一种基于相位历程响应的高分辨力雷达地面运动目标的信号特征分析方法。在分析总结了高分辨力雷达地面运动目标特征的基础上,对仿真的雷达数据作了深入的理论分析,包括对数据模型以及相位和幅度的分析。首先,特征数据中的相位信息同样值得提取和研究;而且,雷达视角上顺序特征数据的相位信息可以反映散射点之间的相对位置。这些结论在雷达目标识别中具有重要的指导意义。

An analysis method for ground moving target HRR signature based on phase history response model was presented.On the basis of analyze and summarize features of HRR ground moving target,this paper conducted comprehensive theoretical research of simulated HRR signature,including HRR signature modeling and analysis of phase and amplitude of the signature.First,the phase of complex signatures is uniformly worthy of being researched,and the phase may provide extra knowledge regarding scatterer relative locations...
