propagation of error

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。

Software defects are inevitable, however, the software reliability is relates to the probability of errors when software is running. Thus, to improve the software reliability, the control of software defects propagation and find error tendency modules are very important.

软件缺陷是不可避免的，而软件的可靠性是软件在运行时错误出现的频率，因此要提高软件的可靠性，其中控制软件缺陷传播、寻找软件的错误倾向模块就显得非常重要。

The idiographic behave is that after certain distance propagation, the signal strength of sky wave will exceed the strength of ground wave apparently, it makes the receiver lock on the sky wave by error and the positioning result will deviate from the actual position.

其具体表现为：在传播一定距离后，天波信号强度远大于地波，导致接收机错误的锁定在天波上，使系统解算结果偏离实际载体位置。
