从理论上分析了入射到高速列车车体上的垂直极化平面波在车体上产生的二次辐射场.利用爱因斯坦相对论和正反2次洛伦兹变换,得到了经过列车体的反射波解析式、二次辐射场的频率和反射角等参数.反射波频率和反射角不再遵守反射定律,而是与速度、入射角和方位角有关的函数.当y方向速度大于或等于0时,反射角均小于或等于入射角;y方向速度小于0时,反射角则大于入射角.随着入射角的增大,反射频率和入射频率之间的差距越来越大;随着y方向速度的增大,两者之差也逐渐增大.最后通过仿真计算和实测数据验证了理论分析的正确性.
The secondary radiation field generated by the vertically polarized plane wave incident on the body of a high-speed train is analyzed theoretically.Using Einstein’s theory of relativity and the positive and negative Lorentz transformation, the reflection of the train body Wave resolution, the frequency and reflection angle of the secondary radiation field, etc. The frequency and reflection angle of the reflected wave no longer obey the law of reflection but a function related to velocity, angle of incidence and azimuth When the y-direction velocity is greater than or equal to 0 The reflection angle is less than or equal to the incident angle, and the reflection angle is larger than the incident angle when the y-direction velocity is less than 0. As the incident angle increases, the difference between the reflection frequency and the incident frequency becomes larger and larger; as y The difference between them increases gradually.Finally, the correctness of the theoretical analysis is verified by the simulation calculation and the measured data.
