摘　　要：对光学区扩展目标的散射特性进行分析,建立了基于多散射中心及线性调频体制宽带雷达的目标回波模型,同时给出了雷达回波数据的存储模型及处理方法。在此基础上对扩展目标作径向和非径向匀速直线运动两种情况下的回波信号进行模拟仿真为验证回波模型的正确性,对仿真的回波数据分别进行脉冲压缩和多普勒处理,得出的目标的一维距离像和速度维正确地反映出目标特征,表明模型可行有效,为后续的目标特征提取、目标识别奠定了基础。In the paper,the scattering properties of extended targets of Optical zone were analyzed,the LFM radar echo model based on multi-scattering centers was established and the storage model and approach of echo data was also given.On the basis,extended target echo signal for radial and non-radial uniform linear motion in both cases was generated.The simulated echo data was processed by pulse-compression and Doppler processing to verify the validity of echo models.The result finally reflected the characteristics of targets and thus the model was feasible and effective and laid the foundation for future target feature extraction and object recognition.
