| 摘 要： | 对整机雷达散射截面(RCS)进行快速预估分析.将军用飞行器散射总场分成两部分进行估算,对于机体表面单元散射场贡献采用电磁场的高频模拟计算方法即物理光学算法(PO),对于机体外延及面相交部所形成的棱边绕射场贡献采用改进的等效电磁流(IMEC)算法分析.为了验证该算法的有效性,完成了对两种飞行器目标模型RCS的模拟计算.模拟结果与暗室实测结果对比,表明该算法可以满足工程估算要求.

| Abstract: | The fast computing method of radar cross section(RCS) for military aircraft stealth designing is an important research subject.The proposed method employs physical optics calculation(PO) to compute the scattering contribution of the surface unit cells and uses the improved method of equivalent currents(IMEC) algorithm to compute the wedge scattering contribution of target edge consisted of the crossing surface.The scattering field of total target includes above two parts of contribution.Having the models of... |
