水下目标辐射声信号重构效果比较研究

Research on Comparing the Performance of Underwater Target Radiate Acoustic Signal Reconstruction Methods

研究相空间重构是混沌分析过程中的重要环节,会直接影响重构空间上的混沌分析的结果,也直接影响水下目标辐射信号分析效果。为检验不同重构方法处理水下目标辐射声信号的效果,仿真了几种常用的重构方法:自相关&G_P方法、奇异值方法、C_C方法,针对水下目标辐射声信号,比较各种方法的差异,找出重构效果较好的方法。仿真结果证明:对于水下目标辐射声信号,自相关&G_P方法、奇异值方法重构的效果比较好,而C_C方法重构效果不佳。所以,在分析水下目标辐射声信号时,可以采用相关&G_P方法、奇异值方法,以便得到更好的分析效果。

State Space Reconstruction is an important part in chaotic analyzing, it directly influences the result of chaotic analyzing. In order to testing the performance of different reconstruction methods on processing underwater target radiate acoustic signal, simulate several reconstruction methods, such as Autocorrelation ＆ G_P method, SVD method, C_C method, compare different methods to find the most suitable method for processing underwater target radiate acoustic signal. It＇s proved that the Autocorrelation ＆ G P method and the SVD method do well on processing underwater target radiate acoustic signal, but C_C method does bad. So in order to get better analyzing result we can use the Autocorrelation ＆ G P method and the SVD method to process underwater target radiate acoustic signal from now on.
