摘要

Abstract

Statistical characteristics of sound pulses and some typical marine noises in a shallow sea were analysed. With special requirements for underwater telemetric and telecontrolled devices in mind

a specific signal processing scheme (digital correlation accumulation) is put forward. Theoretical analyses on some underwater acoustic instruments showed this signal processing scheme is applicable to a shallow acoustic channel with variable spatiotemporal characteristics

multipath pulses and high noise level

and may be of general significance for underwater acoustic telemetry and telecontrol.
