在机载站飞行方向前方某一距离处的多普勒频移能够通过递推计算的方法由站点当前位置处的相位测量结果而被直接确定。进一步利用频移和角度之间的变换，由多普勒频移的虚拟递推值即可求得载机飞行路线前方虚拟距离处的目标方位，由此就可在机载单站平台上通过三角定位法，实现仅基于相差测量的无源测距。

Doppler shift at a certain position in front of the flight direction of airborne station can be directly determined by recurrence method and by making use of the measurement result for phase difference at current position. Furthermore, using transform between Doppler shift and angle, the target's azimuth can be determined by dummy recurrence value of Doppler shift at dummy position in front of the flight direction of airborne station. Therefore, the passive ranging only based on phase difference measuring can be realized by triangle position fixed on single airborne observer platform.
