Dwell scheduling of multifunction phased array radars based on genetic algorithm

A dwell scheduling model which takes the time and energy constraints into account is founded from the viewpoint of scheduling gain. Dwell scheduling strategy design is turned into a nonlinear programming procedure. A dwell scheduling algorithm is then given based on the genetic algorithm. Simulation results demonstrate that compared with the conventional adaptive scheduling method, the proposed algorithm not only increases the scheduling gain and the time utility of the system but also decreases the task drop rate.
