摘要
Abstract
The traditional underwater acoustic signals applied in underwater acoustic confrontation exercises which are likely to reveal the position of submarine itself are difficult to form an effective multi-confrontational situation between red and blue, which will result in inefficient and ineffective exercises. Low probability of intercept underwater acoustic signals can effectively over?come the shortcomings of traditional underwater acoustic signals,while the large computation limits their applications. So a fast de?tection algorithm based on multiple correlation,downsampling and fourier transform is proposed to reduce the computation and ex?pand the application of low probability of intercept underwater acoustic signals in underwater target positioning of range under the premise of guaranteed detection accuracy. Finally,some simulation results and analysis of the algorithm are presented to verify its validity.关键词
