本文首先探讨浅海声信道中多途的统计特性,在此基础上分析了DTCCA和DTACA抗多途的性能。理论估算和实验证明,这类信号处理方式抗多途性能是优越的,可以利用多途能量。
In this paper, the statistical characteristics of multi-pass in shallow ocean acoustic channel are firstly discussed, and the performance of DTCCA and DTACA against multi-path is analyzed. Theoretical estimates and experiments show that this type of signal processing is superior to multipath performance and can take advantage of multipath energy.
