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。

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 sta-tions fully,a new recursive algorithm for passive target location with bearing-only measurements is pro-posed. The simulation results show that the location precision is enhanced and the given covariance can re-flect the true statistical distribution of the target position. Therefore the proposed algorithm deserves to be put into practice for an engineering application.
