Abstract:

The correct mutuality judgment of fusion track and true track is the basis of the capability evaluation for the multi-sensor data fusion.The detecting precision of sensor has great influence on the capability of fusion system.This paper presents a new technique of fusion track judgment which calculates detecting precision of every sensor participating in data fusion and makes the precision as the judgment distance threshold of fusion track and true track,thus improving the processing efficiency and accuracy of judgment.Engineering applications prove the feasibility of the algorithm.

Key words: multi sensor;detecting precision;fusion trackjudging
