基于实测数据的宽带雷达回波半实物仿真方法

自动目标识别技术的发展对雷达回波仿真的要求越来越高。分析了散射点回波叠加法和电磁散射建模回波生成法各自的优缺点，结合两种方法提出了基于实测数据的雷达回波半实物仿真方法。首先通过电磁散射建模预估目标的RCS信息，再从实测回波数据中提取目标的运动特征，从而仿真出雷达回波。该方法灵活性好、精度高、易于工程实现，仿真出的回波成像后具有较清晰的轮廓和明显的运动特征。

Method of HWIL simulation for wide-band radar echo based on measured data

With the development of automatic space target recognition technology,methods of simulation for radar echo attract more and more attention.The methods of simulation using scatters echo superposition and modeling electromagnetic scattering are analyzed,and a new method based on the real echo data is presented.The new method makes use of modeling electromagnetic scattering to get RCS information and extract movement features from radar echoes,then achieve the target of simulation.The new method is easy to rea...
