摘　　要：动态回波数据是研究空间微动多目标探测与识别的基础。基于散射中心模型研究了双基地雷达微动多目标回波仿真方法。首先,分别为各个空间微动目标建立相应的观测坐标系;然后,根据微动模型求解目标散射中心在观测坐标系下的位置,再将观测坐标系下的散射中心坐标转化到基准坐标系;最后,求解微动距离变化并结合双基地可视条件进行回波仿真。动态仿真和电磁计算仿真结果验证了所提方法的有效性,可以广泛应用于空间微动多目标成像、特征提取等多个领域的研究。Dynamic echo data is the basis for studying the detection and recognition of space micro-motion multi-target.The micro-motion multi-target echo of bistatic radar simulation method based on the scattering center model is studied.Firstly,this method establishes the corresponding observation coordinate system for each space micro-motion target.Then,the positions of the target scattering centers in the observation coordinate system are solved according to the micro-motion model,and the scattering center coordinates in the observation coordinate system are transformed into the reference coordinate system.Finally,the variation of micro-motion ranges are solved for the echo simulation combined with bistatic visual conditions.The result of dynamic simulation and electromagnetic calculation simulation validates the effectiveness of the proposed method,which can be applied in the research of space micro-motion multi-target imaging,feature extraction,and other fields.
