摘　　要：在一致性几何绕射理论基础上，采用等效电流的方法给出了有限锥体在完全极化平面波照射下后向散射场的散射极化矩阵表示式。通过能量散射矩阵［Ｇ］得出最佳散射的极化条件。由米勒矩阵［Ｍ］分析了相差的密度函数，并得出各自相应的数值结果。Based on the uniform geometrical theory of diffraction,the equivalent current is used to calculate the back scattering field for the finite cone. Then the scattering matrix including information of polarization is gotten,assuming that the incident wave is complete planepolarized wave,and the optimized state of scattering polarization is worked out through energy-scattering matrix. The probability density functions of the co-polarized and cross-polarized phase differences are analyzed by Muller matrix and the numerical results are also given.
