Abstract: Power control for a radar system issues power draw commands to each array in the radar system. Each power draw command controls direct current (DC) power draw by the respective radar array on a dwell-by-dwell basis, based on total energy resources (including stored energy) available to the respective array at the start of a dwell period, a power spend rate expected for the respective array during the dwell period, and a rate of “waste” power set to be dispersed to reduce excess power at the respective array during the dwell period. In determining power draw for an array, the power control takes into account a predetermined number of future dwell periods and any transmit and/or receive tasks scheduled for such periods. If necessary to maintain less than a predetermined ripple on total DC power drawn from a source of the DC power by the radar system, the power control adjusts a duration of empty dwell periods within the dwell schedule for one or more of the arrays.
