摘要：
This paper researches on the relative navigation of a chaser tracking a non-cooperative maneuvering target based on measurements from radar. A novel relative navigation algorithm is proposed. This algorithm is not only robust to these outliers included in measurements, but also quickly convergent when unknown maneuvers happen. Two new filters, named DDF2-STF and DDF2-Huber are designed respectively, and a strategy determining which filter should be used according to different situations is composed thus developing the novel algorithm. The simulation results show validity of the algorithm.
