一种利用交会角改善双站测向准确性的方法

Method Improving DF Veracity of Two Stations by Using Cut Angle

借助几何投影的方法可得到一个与几何参量相关的程差方程,由此可得到一个基于双站间程差与交会角测量的长基线测向解析解,在此基础上通过近似简化即可得到一个形式简单,准确度亦很好的双站测向式,且由此表明,利用双站间的交会角能有效地改善现有双站测向解的准确性。

In virtue of geometric projection, the path difference equation can be obtained which is associated with geometricparameter. Thus, the DF analytic solution for long baseline can be derived based on the path difference and cut angle between twostations. On this basis, a DF formula for two stations, that the format is simple and veracity is also good, can be obtained byapproximate reduction. The analysis result shows that using cut angle between two stations can effectively improve the veracity ofexistence DF solution of two stations.
