Abstract
On the basis of the tracking multi-loop target angle coordinate system, the article has selected and proposed an interactive multi-model adaptive filter algorithm to improve the quality of the target phase coordinate filter. The interactive multimodel evaluation algorithm is capable of adapting to the maneuverability of the target as the evaluation process progresses to the most suitable model. In which, the 3 models selected to design the line of sight angle coordinate filter; Constant velocity (CV) model, Singer model and constant acceleration (CA) model, characterizing 3 different levels of maneuverability of the target. As a result, the evaluation quality of the target phase coordinates is improved because the evaluation process has redistribution of the probabilities of each model to suit the actual maneuvering of the target. The structure of the filters is simple, the evaluation error is small and the maneuvering detection delay is significantly reduced. The results are verified through simulation, ensuring that in all cases the target is maneuvering with different intensity and frequency, the line of sight angle coordinate filter always accurately determines the target angle coordinates
