Fuse On The End Of The Torpedo Trajectory Correction Study

This paper mainly discusses the vital part discrimination of the near-field target by using target acoustic imaging method, which uses dense narrow beams based on high frequency system. The operating frequency , acceptance range and other essential parameters are confirmed. The high frequency array is designed. The amplitude feature and the phase feature of target highlights are acquired, and two cluster methods based on the two features are proposed. Interference background is wiped out by cluster analytic methods , and distinct target image is achieved. System signal process simulation software is compiled and the basin small-scale model experiment is carried out.
