Basing on the practical use, the character and performance of direction of arrival method is specially studied, while a method to estimate the position of emitter based on probability distribution characteristics of bearing measurement errors is introduced. 基于实际应用背景,重点研究了测向定位算法的特点以及性能,并在文中提出了一种根据测向误差概率分布特性估计目标位置的方法。
