| 摘 要： | 为了建立整机近场电磁雷达散射截面（RCS）的理论模型，以三角形三面角反射器回波响应图为参考，拟合正方形三面角反射器的电磁散射RCS数学模型。同时以正方形三面角反射器方向图曲线的数值对理论模型进行验证。其精度为：算术平均误差d=1.3dB,标准偏差S＝1．5dB，从而说明本模型可以参与整机理论模型的建模。

| Abstract: | In order to establish a theoretical model of near field EM scattering, this paper, with reference to the echo pulse response of the triangle trihedral angle reflector, fits the methomatical model of the square trihedral angle reflector and verifies the theoretical model with the number value of the directional diagram curve of the square trihedral angle reflector. The precision of the model is as fatlows: arithmetic mean error d =1.3dB and standard deviation S =1.5dB. |
