传统的测向定位理论在对多个目标进行定位时，将测得的DOA参数按目标进行分类是一个难点问题。运用位置信息场定位法不需要对测量参数按目标进行分类，能够同时确定目标数目和多个目标位置。对基于DOA测量的多目标位置信息场定位方法进行了精度分析，通过理论推导得到定位误差的协方差矩阵。在此基础上，利用仿真实验分析了测角精度和基线长度对定位精度的影响，验证了理论推导的正确性，说明了位置信息场定位法是一种有效的多目标定位方法。

When the traditional direction finding positioning theory positioning on multiple targets, how to classify the measured DOA parameters by the target is a difficult problem. The position information field location method has the advantage of getting the number of targets and finding the multi-target’s position at the same time without classifying the measurement parameters according to target. Precision analysis for position information field location based on DOA is presented and positioning error covariance matrix is given. Based on it, the influence of the measuring angular accuracy and baseline length on the location accuracy is analyzed by computer experiments and it proves the correctness of the theory analysis and the effective of the position information field location method to multiple targets.
