摘要：

This paper describes the signal processing scheme used in sources and receivers for the remote acoustic measurement of the oceanic sound velocity field. Ocean sound velocity varies in response to interior dynamic processes so that a continuous sound field measurement is expected to provide a unique view of physical oceanographic phenomena. The basic signal processing technique uses maximal length shift register sequences with frequency-domain (nonpower of 2 FFT) matched filtering. © 1979 IEEE
