Abstract:

This paper develops the measuring model of image centroid based on imaging sensor, and then converts it to the angular measuring one. The measuring model based on radar sensor is also presented. The difference between the measuring models of two sensors are considered and the fusion models are studied emphatically. In consideration of the asynchronous problem of data from two sensors, a time aligning between the asynchronous data based on least square technique, and fusion method are presented. A tracking filter is also designed and the simulation results for each case are given, which shows the superior performance of the fusion models.

Key words: target t rack ing, measurement models, data fusion, t ime aligning
