| Bibliography: | 31-1577/TN labeled multi-Bernoulli filter; infrared search and track; maneuvering targets; track-before detect; interacting multiple models Labeled M ulti-Bernoulli（ LM B） filter was proposed based on classic M ulti-Bernoulli filter by taking label space into account. It is a true trajectory filter in comparison with other methods. The motion model and measurement model of infrared small targets were studied. The LM B Track-Before-Detect algorithm was applied to detect and track infrared small targets. In order to detect and track multiple maneuvering targets with time-varying motion models,an IM M-LM B Track-Before-Detect algorithm was proposed by integrating the interacting multiple models（ IM M） with LM B Track-Before-Detect filter. The sequential M onte Carlo（ SM C） implementation for IM M-LM B track-before-detect was also given. Simulation results demonstrate that the proposed algorithm can detect and track multi-targets trajectories from rawimage. In addition,it can update the model probability in an onli |
