摘　　要：研究了基于3D建模的一维距离像仿真方法。首先,对复杂目标进行3D几何建模,并对其进行合适的剖分,通过模型处理导出剖分单元信息;然后,对各个剖分单元的RCS进行电磁建模计算,整个复杂目标的回波可以看成是各个剖分单元回波的叠加;最后,将回波进行脉冲压缩就可以得到该复杂目标的一维距离像。仿真结果表明了该方法的有效性,同时还给出了两种舰船目标的一维距离像。A method of simulating high resolution range profiles based on 3D modeling of radar targets was researched. Firstly, the 3D geometry model of a complex target was made and split properly, and the geometrical information of every split unit would be obtained by modeling processing. Secondly, computed every unit＇s RCS based on its electromagnetic model and the echo of a complex target could be re garded as the sum of every unit＇ echo. Finally, the high resolution range profiles of a complicated target was obtained by pulse compressing. The simulation results show that this method is effective and give the high resolution range profiles of 2 kinds of ships.
