Coherence estimation for repeat-pass interferometry
2014
2014 Oceans - St. John's
Repeat-pass interferometry is an extension of Synthetic Aperture Sonar (SAS) that exploits the temporal characteristics of seafloor reverberation by coherently combining echoes from multiple passes of the sonar platform. In order to achieve pass-to-pass coherence, the spatial separation between passes must be less than a value known as the critical baseline, which depends on the sonar parameters and the range-dependent imaging geometry. The temporal separation between passes must also be less
