| 摘 要： | 采用远场双站雷达散射截面计算方法进行复杂目标近场双站雷达散射截面的预估.在近场条件下,入射波是球面波照射,不满足远场条件.因此,通过把电大尺寸复杂目标剖分成若干电小尺寸的多边形面元,使每个面元满足远场条件,应用物理光学法和增量长度绕射系数法来求解单个面元的双站雷达散射截面,同时考虑天线方向性因子对近场的影响,可获得复杂目标总的近场双站雷达散射截面.利用该方法可以有效地完成复杂目标近场双站RCS估算. |
| 关 键 词： | 近场 双站雷达散射截面 双站散射 面元 |

| Abstract: | A method of far-field bistatic radar cross-section(RCS) calculation method was studied to estimate the near-field bistatic RCS of complex targets in this paper.Under the near-field conditions,the incident wave is a spherical wave,so the far-field conditions can not be satisfied.Therefore,it is assumed that the complex targets have been decomposed into a number of smaller polygon facets,each of which can meet the far-field conditions.Then,each facet's bistatic RCS can be solved using physical optic(PO) and t... |
