两种目标定位方法的误差分析

摘要

Single station spherical coordinates localization algorithm and gradient method are often implemented on target localization.The theories and error processing of the two methods were presented, and the localization accuracies were compared by theory analysis and calculation.The result shows that gradient method is more accurate than single station spherical coordinates localization algorithm.%单站球坐标定位法和梯度法是目标定位中经常使用的2种方法.针对2种目标定位方法的定位精度问题,分别介绍了2种方法的原理及误差处理过程.通过理论分析和仿真计算对上述方法的目标定位精度进行比较,结果表明,梯度法比单站球坐标定位法具有更高的目标定位精度.
