A Template-Based Adaptive Radar Dwell Scheduling Algorithm

This paper addresses the scheduling problem of radar dwells in multi-function phased array radar systems. A reasonable dwell model for pulse interleaving is built, and its parameter is little affected by target’s state. Therefore the type of dwell can be predicted, and dwell templates can be designed off-line. The on-line scheduling algorithm takes both the priority and deadline into account, and schedules according to the chosen template under timing and energy constraints. Simulation results indicate that compared with the conventional algorithm, both for track and search, the one can decrease missed the ratio of dwell effectively.
