摘　　要：为了满足雷达目标识别的需求,提出了一种在海面背景下仿真船舰目标雷达散射截面积(RCS)和高分辨距离像(HRRP)的方法。利用FEKO软件进行仿真得到目标RCS,对比不同仿真方法的仿真效率。仿真船舰海面混合模型的散射特性,对频域回波数据进行IFFT得到海面背景下船舰模型的高分辨距离像,仿真结果表明,在海面背景下运用FEKO获取高分辨距离像的方法仍具有有效性,可以用于雷达目标识别。In order to meet the requirements of radar target recognition,this paper proposed a method to simulate the radar cross section(RCS)and high resolution range profile(HRRP)of ship targets under the sea surface background.The RCS of the target was obtained by simulation with FEKO software,and the efficiency of different simulation methods was compared.The scattering characteristics of the mixed model of the ship sea surface were simulated,and the high-resolution range image of the ship model under the sea surface background was obtained by IFFT on the frequency domain echo data.The simulation results show that the method of obtaining the high-resolution range image by FEKO under the sea surface background is still effective and can be used for radar target recognition.
