Abstract

Since phased array radars have the ability to perform adaptive sampling of the target trajectory by radar beam positioning, proper control of the radar has the potential for significantly improving many aspects associated with the tracking of multiple maneuvering targets. When supported by additional sensors, the sampling of the phased array radar can be reduced significantly. However, controlling the revisit times of the phase array radar becomes more difficult. The technique proposed in this paper uses the Interacting Multiple Model algorithm to track maneuvering targets and control the radar revisit time and pointing when the radar is supported by a Precision Electronic Support Measures (PESM) sensor. Algorithms for tracking with multiple sensors, computing the radar revisit time, and pointing the radar are presented in this paper. Performance comparisons are given with the radar using adaptive data rates and the PESM providing measurements at regular intervals and intermittently.
