Abstract
A mode scheduling system for selecting track or search dwells in a track-while-scan radar. Targets to be tracked are classified according to acceleration levels and then arranged into priority classes based upon the acceleration. A relative update frequency for the targets in the priority classes is established. The track and search dwells are made during a repetitive dwell period having a predetermined number of track dwell intervals. Track dwells are scheduled during these intervals to satisfy the update frequency requirements. When all of the track dwell positions are not needed, search dwells are substituted for some of the track dwells. Search dwells are also inserted between track dwells, as needed, to maintain a minimum amount of search time regardless of the number of targets being tracked.
