中文摘要：

修磨位置的确定是天线-罩系统电性能优化的关键。基于平面波谱-表面积分（PWS—SI）算法，分析面天线在扫描过程中辐射变化情况，研究了最大瞄准误差扫描角的存在性。并且依据正切卵形天线罩内廓面型值点数据，利用Gaussian正态分布函数进行拟合，计算出瞄准误差最大时天线主轴方向与罩壁的交点位置。并假定交点位置附近为天线-罩系统电磁敏感区，可以作为最佳修磨位置，最后通过不同位置修磨仿真验证了该假设的正确性。

英文摘要：

The grinding location is the key in electrical property optimization of Antenna-Radome System. When the electromagnetic radiation changing existence of maximum boresight error scan angle has of antenna is analyzed based on PWS-SI,the been authenticated. Based on the tangent ovate radome shape data, Gaussian normal distribution function is used to fit the curve,and the crossing point location of the antenna wall and the maximum boresight error radiation electrical axis direction are figured out. In the end the hypothesis about the optimum grinding location is propounded for Antenna- Radome System, and the validity of the hypothesis is proved through simulation.
