Tracking Anti-Ship Missiles Using Radar and Infra-Red Search and Track: Track Error Performance

摘要

The problem of association and fusion of radar and infra-red search and track (IRST) sensor reports is not straightforward, especially because IRST provides only angular measurements while radar provides range and range-rate measurements in addition to azimuth and elevation measurements. In this report, simulation results show that a centralised extended Kalman filter tracker is a solution that can capitalise on the higher angular accuracy of the IRST sensor to provide improved track accuracy performance.
