摘　　要：从极化的椭圆参数与极化球的Stokes参数的关系出发 ,直接推导出干扰环境下极化球面上的优化接收信号干扰噪声比参量表示式。该式对极化优化接收和信号增强很有用处。尽管难以得到全局最优解析解 ,但仍比较详细地给出了小圆和大圆轨道下的局部最优解 ,并进行了仿真。An equation for the signal to interference plus noise power ratio about optimal reception on the polarization sphere in interference environment is derived directly based on the relationship between ellipse parameters and Stokes parameters. This equation is very useful for the polarization optimization reception and signal enhancement. Although it is rather difficult to obtain the globe optimal analytical solution, the local optimal solutions on small circle tracks and great circle tracks are presented in detail, and some simulation results are investigated.
