Performance analysis of target tracking for radar network in the presence of stand off jamming

Abstract

In the presence of stand off jamming, a new radar observation equation was proposed for radar network, and anti-jamming measure's influence on performance of target tracking for radar network was analyzed based on the new radar observation equation. The observation equation calculated the detection probability based on signal-to-jamming ratio (SJR) of radar receiver and then simulated sensor's targets detection condition in the presence of stand off jamming. The influence of non-coherent integration improvement factor, pulse compression (PC) time-bandwidth product and SLC cancellation ratio on performance of target tracking for radar network was analyzed after radar taking anti-jamming measures. Simulation result shows that radar network taking anti-jamming measures can prolong the time of track continuance, while it has no symptom improvement on performance of tar-get tracking for radar network. © 2013 Springer Science+Business Media.
