propagation of microwave

A half-transparent plate is put before the microwave detector with its plane perpendicular to the direction of propagation of the microwave. The wavelength of microwave can be determined by moving the plate and the results obtained by this method are the same as by the Michelson interference method.

在微波接收器前放置板面垂直于波传播方向的半透平板，沿波传播方向移动板的位置可以测量微波的波长，测量结果与用迈克耳逊干涉法测量的结果相同。

The error of missile speed was deduced by the distance error. The distance error was obtained by a microwave radiometer directly detecting the atmospheric radiation brightness temperature on the path of radio wave propagation.

其速度（距离变化率）误差是利用与距离误差△R之间的关系得到，而△R由微波辐射计在电波传播路径上直接测量大气辐射亮度温度得到。

Compared with optical detector, radar has the advantages of all weather detection and detection distance due to the different propagation characteristics of optical wave and microwave in the air.

由于光频段电磁波和微波频段电磁波在空气中传播特性的不同，因而相较于光学探测器来说，雷达具有全天候、探测距离远等优点。
