传递对准的一种方位估计方法

以往的速度匹配方法通常水平失准角估计精度很高,对准时间快而方位失准角估计不理想，为了克服这个问题，本文推导了一种新的方位估计方法。首先由新的速度匹配方法估计出两个水平失准角，然后把这两个失准角信息当做已知量，计算出了方位失准角。并且根据理论推导进行了仿真，结果表明，该方法估计方位失准角精度高，有很好的实用性。

A Azimuth Estimation Method for Transfer Alignment

he accuracy of leveling alignment is high and fast but the accuracy of heading alignment is not the ideal situation generally in the method making use of matching in the past. In order to overcome this problem, this article deducing out a new alignment method. First of all, by a new velocity matching to estimate the two leveling installation error angle, then we regard the leveling alignment information as known quantity, calculate the azimuth installation error angle. And simulation according to the theories, the results show that, this method estimates the accuracy of heading alignment is high, from good usability.
