Many tasks compete for resources. Some resources, such as the round trip propagation or waiting time are reusable (we can transmit in another direction while waiting) while other resources, such as the receive time, are not even preemptible. Real-time optimum scheduling that maximizes a quality-of-service metric called utility under fixed resource constraints is not computationally feasible. Recent real-time computer systems research, however, has produced feasible approximations to optimum scheduling, even in complex dynamic environments. We propose to apply these techniques to airborne AESA-based radar systems of interest to the Navy. Benefits: Radar resource management algorithms and evaluations will be an essential ingredient of an end-to-end radar system performance modeling tool for the evaluation of candidate radar architectures. Real-time resource scheduling applies to all embedded computer systems, accounting for more than 98% of the processors produced. Return
