多站测向定位新算法

无源测向定位在信息对抗、导航等领域应用非常广泛。针对如何充分使用同时获得的多站测向数据，提出由两站向多站逐渐递推的目标定位新方法。仿真结果表明，最终定位精度得到了提高，给出的协方差能够真实反映目标的分布概率，新方法具有一定的工程应用价值。

A new target location algorithm with bearing-only measurements

Passive direction finding(DF) of emitter source is widely applied in the fields of information countermeasure,navigation,etc.Aiming at the problem of how to use the simultaneous DF data of many stations fully,a new recursive algorithm for passive target location with bearing-only measurements is proposed.The simulation results show that the location precision is enhanced and the given covariance can reflect the true statistical distribution of the target position.Therefore the proposed algorithm deserves to be put into practice for an engineering application.
