Abstract:It is important to optimize sonobuoys deployment for enhancing cumulative detection probability in aviation ASW. Firstly, the target motion model was established and method of calculation cumulative detection probability was interpreted. Then three kinds of global optimization algorithms were designed validly for sonobuoys deployment, based on multi-start random search, branch-and-bound based partition and a genetic algorithm. The simulation results showed that the multi-start random search algorithm was comparatively weak but fit for give deployment scheme in short time, branch-and-bound based partition algorithm could reach optimization but only fit few sonobouys array parameters, and GA was fit for sonobouys array with many parameters but need long time to calculate.
