提出利用测量设备与辐射源相对运动速度及测量设备所接收到的辐射功率的估算测量设备到辐射源距离的一种方法。对计算精度进行了分析，通过算例对理论分析进行了检验。

The paper proposes a method to calculate the distance between the missile and the radiant source by measuring the radiation power of radiation source and relative speed between the missile and the radiation source. This paper analyzes the calculating precision by error theory and a calculation example.
