The Study of Adaptive Line Spectrum Enhancement By Pressure and Particle Velocity Combined

摘要：

In order to solve the problem of underwater acoustic target detection and identification in the lowfrequency , long-range , advantages of the vector hydrophone characteristics which measures three dimensional acoustic particle velocity vector, as well as the acoustic pressure at one location, are used to improved the acoustic pressure adaptive line spectrum enhancer. Analysis of simulation data under different SNR and measured target radiated noise data show that the performance of pressure and particle velocity combined adaptive line enhancer on target radiated noise characteristic line spectrum is indeed better than the traditional ones in low SNR cases.
