摘要
微动产生的微多普勒特征是弹道目标微动参数提取与识别的重要依据。首先基于组网雷达,分析弹道目标中3种典型的微动模型,得到微距离关于雷达观测视角的参数化表示,然后分别针对窄带雷达和宽带雷达作回波分析,最终得到雷达观测到的弹道目标微多普勒效应与雷达观测视角以及信号参数的关系,后面的仿真验证了理论分析的正确性。
Micro-Doppler induced by micro-motion is the key point to the micro-motion parameters estimation and recognition. Firstly,based on the netted radar,three kinds of the prototypical micro-move models are analyzed and the parameterization of micro-range about the visual angle is got. Then,the echoes of narrow-band radar and wide-band radar are analyzed. Finally,the relationship between microDoppler effect,the visual angle and the signal parameters is got. The simulation results verify the theoretic analysis.
