Research of Active Detection Technology Using Vector Array on Small Platform

Abstract:

Active sonar on small platform which uses vector array is selected in this paper as research object, the methods of signal and DOA estimation and the performance of these methods are discussed. Vector array comprehensive copy correlator and vector array comprehensive adaptive copy correlator which use acoustic pressure and vibration velocity at the same time are proposed in this paper. The performance of signal processing and the precision of DOA estimation can be improved by these methods. Simulation results present that the performance of the proposed methods are better than conventional copy correlator. In addition, vector array comprehensive adaptive copy correlator has higher gain than vector array comprehensive copy correlator in multi-path channel.
