Abstract

This paper addresses the problem of scheduling radar dwells in multi-function phased array radar systems. The timing constraint of radar tasks are usually modeled by the minimal and maximal temporal distance between any two consecutive dwells of a task. Such a timing constraint makes it difficult for traditional real-time scheduling techniques to provide predicatable timing guarantee, without over-consuming the resources. We propose a novel approach to model the dwells as periodic real-time tasks. The periods of the tasks are synthesized by the minimal and maximal temporal distance constraint of the dwells. The synthetic periods allow the template-based scheduling algorithm to compute efficient dwell schedules with low overhead. We evaluate the algorithms via extensive simulations. Simulation results show that this algorithm can significantly improve the resource utilization.
