| 摘 要： | 为了预估复杂目标的近场雷达散射截面(RCS),通过图形电磁计算方法(GRECO)来求得复杂目标远场散射中心的雷达散射截面,采用z-buffer遮挡消隐技术来提取面元远场散射中心的位置,然后给出一种预估复杂目标近场RCS的方法.在雷达天线与目标之间的距离不是太近的情况下,通过仿真目标的远场和近场RCS的分布情况,并对其结果进行比较分析.可以证明该方法计算出来的近场RCS是有效的、准确的,可以应用到实际工程中去分析和解决问题.

| Abstract: | Radar cross section (RCS) of the near-field scattering of complex targets is studied. Firstly,radar cross section of the far-field scattering centers of complex targets is calculated using the Graphical Electromagnetic Computing (GRECO) technique. Then,the location of the far-field facets scattering centers is extracted by the z-buffer technique. Finally,the method is presented to predict the near-field radar cross section (RCS) of complex target. When the distance between target and radar antenna is short,... |
