摘要
在已有的一维直线阵测距式的基础上,以双站间基线方向为基准,通过测量各个子站内短基线阵列相对于基准方向的偏转角,求解出等效的到达角和路程差,从而实现对短基线方位的修正。误差分析表明,短基线阵列相对于基准方向的偏转角的测量误差对整个相差测距精度具有较大的影响。
Based on existing ranging formula obtained according to one-dimensional linear ar- ray and taking the baseline direction between two stations as location measuring basis, the e- quivalent arrival angle and path difference can be solved by measuring the deflection angle of short-baseline array relative to reference direction for each station. Accordingly, the correct for short-baseline azimuth can be realized. The error analysis shows that measuring error brought by the deflection angle has biggish influence for the ranging precision based on phase difference measurement.
