PROJECT TITLE :

Cooperative track initiation for distributed radar network based on target track information

ABSTRACT:

Distributed radar network will considerably improve target localisation accuracy as long as targets will be successfully tracked by all radar sites. But, since completely different radar sites usually have totally different signal-to-noise ratios with respect to even the same target, it's tough for all radar sites to trace a target simultaneously. During this case, the authors propose a cooperative track initiation algorithm for distributed radar network. It aims to improve track initiation performance of invisible radar sites that have not initiated the target track, by using target track info provided by the radar sites that have tracked the target. Primarily based on the target track data, the invisible radar sites would predict a region where the target can be gift, and decrease detection thresholds in the expected region in keeping with a given probability of false track initiation. Numerical results indicate that the proposed algorithm can significantly improve the probability of target track initiation.
