Passive Acoustic Direction Finding UnderMultiple Targets Conditions

Aim To research acoustic set design of as a fuse system for the anti- helicopter mine adaptable to multiple targets conditions. Methods Several methods for the passive acoustic set design were compared. Set directivities to narrow band and wide band signals were analyzed. Also the acoustic property of helicopter was discussed. Results The set structure adaptable to the multiple target conditions and a target tracking strategy based on the multi- beam- preforming algorithm were proposed. Conclusion Simulation results have proved that the set design and the algorithm are quite available.
