在目标散射问题中,雷达舱和天线罩的散射机理有极大相似之处.在该类散射问题中,电磁波进入腔体时首先在整流罩上进行反射和折射,电磁射线进入雷达舱和天线罩后入射于天线上,天线反射电磁射线,电磁射线透过介质罩形成了散射电磁波.对射线入射于非金属目标的轨迹分裂提出了更为精细的解决方法,并用射线方法计算了该类目标的雷达散射截面. |

The mechanism of EM scattering from targets, radar cabin and radome is very similar. In those subjects EM, those EM rays will be reflected and refracted by radome, then the rays shoot on antenna. After reflected by antenna, then passed through the radome again and become scattering rays. A more picked method is given for solve that questionin, which ray trace will be splinted when EM rays shoot on a non-metal interface. Some results are given by using ray-method. |
