STUDY ON PULSE-PULSE CORRELATION FEATURE OF LOW-FREQUENCY ECHOES FROM UNDERWATER TARGET

摘要

Theoretical and experimental research on the scattering feature of the underwater target and the reverberation channel is the basis of the underwater target's detection and identification, and it's also the feature which the deviser of active sonar is interested in. In this paper we deduce the time relationship feature of channel in theory, get the underwater target's angle correlation feature and its time correlation feature through experiment, together with the experiment result of reverberation channel's pulse-pulse correlation feature.
