在许多情况下，方位是唯一可被利用的用于确定目标所在位置的信息。由于战场信息环境的复杂性，单信息源单滤波器无法满足被动定位时效性和精度的要求。因而，文中根据实际作战需求，分析目前常用的单舰纯方位被动定位方法的特点，提出了基于信息融合的多信息源多滤波器(MSMF)无源被动定位方法，给出了多信息源多滤波器被动定位时各定位结果权值的确定，运用时间序列估计传感器误差方差实现传感器权值的在线调整，仿真结果表明该方法较对单一信息源用单个滤波器进行纯方位被动定位精度有明显提高，对提高单舰纯方位目标定位的能力有一定的意义。

In many situations, the azimuth is the only information source which can be used to determine the position of a target. Because of complicated signal environment in the battle field, the convergence speed and accuracy of the filter is not satis actory when using a single filter for passive location. So, in this paper, according to the requirement of practical operation, the character istics of several kind of filters using only azimuth information are analyzed. Then, a multi-sensor multi filter (MSMF) passive location method is proposed and the weights to the filtering results are given as well as how the adjusting on line of the weigh is can be realized by using time sequence to estimate the error covariance. Simulation results show that it yields significantly improved joint position estimates compared to the results achieved by single sensor single filter. [
