Abstract:

Scaled measurements of the fluctuating acoustical signal resulting from interference of the direct and surface reflected signals from complex targets are reported. Water surface and acoustic autocorrelation functions and spectra are examined for both stationary targets and targets with yaw motion. The scaled surface waves are compared to ocean waves. Author
