    Abstract
  • The covariance matrix of vector hydrophone array output noise is necessary in the array′s design, performance analysis, and simulation of signal processing system. We analyze the output correlation of the vector hydrophone in isotropic noise field and obtain the general formulas for auto-and cross-correlation between two vector hydrophones. With analysis of the probability, a simple method for numerically simulating isotropic noise field is proposed. Numerical simulation results coincide with the theoretical ones, which indicates the proposed method is effective and can generate accurate numerical noise for optimization design of vector hydrophone array and simulation analysis of its signal pro- cessing system.
