Distributed radar spatial registration during searching

摘要

Spatial registration is an essential prerequisite and foundation for multi-radar signal-fusion based detection. In this paper, we present a space registration method that partitions the surveillance volumes into multiple points for signals from widely separated radar sites to align to, so that in the signal fusion centre, signal fusion and target detection are performed over those spatial points. By adjusting the spacing of those spatial points, we can control the signal-noise ratio loss due to spatial partition, as verified by numerical results.
