azimuth accuracy

The accuracy of angle and range estimation of acoustic localization method based on four-element sensor array is influenced by target azimuth angle.

四元十字阵的测向和测距精度受目标方位角的影响，而五元十字阵就可以克服这一缺点。

This paper putted forward network of five-element cross array algorithm, because of location system for passive acoustic array algorithms in four-element cross positioning accuracy affected by the target azimuth.

本文针对四元十字阵被动声定位算法存在定位精度受目标方位角影响的问题，提出基于多基阵的网络五元十字阵算法。

The time of initial alignment is reduced greatly and the accuracy of azimuth alignment is improved.

因此该方法缩短了初始对准时间,改善了方位对准精度.

On the premise of analysis of the factors that influence the accuracy of position fixing, an error model of the azimuth and elevation measurement is built up by Taylor launch.

在分析影响定位精度因素前提下，采用合理的假定建立测向交会定位算法的误差分析模型；
