Source Localization in Shallow Water Using Multi-frequency Processing of Shot Data Source Localization in Shallow Water Using Multi-frequency Processing of Shot Data Source Localization in Shallow Water Using Multi-frequency Processing of Shot Data

Executive Summary: Single-frequency techniques which proved to be successful for source localization in deep-water are shown to be inadequate in littoral areas. To overcome this problem, the processing schemes need to be redesigned to extract and incorporate more information from the received signal and improve the estimates of parameters which describe the propagation channel. This report desc...

Cross-correlation in face discrimination

An extensive body of literature suggests that face perception depends critically upon specialised face processing mechanisms. Although it seems clear that specialised face processing is required to explain face recognition, face discrimination is a simpler task that could possibly be solved with a general pattern discrimination mechanism. Observers were presented with face images that were eith...

Polarization lidar for shallow water depth measurement.

A bathymetric, polarization lidar system transmitting at 532 nm and using a single photomultiplier tube is employed for applications of shallow water depth measurement. The technique exploits polarization attributes of the probed water body to isolate surface and floor returns, enabling constant fraction detection schemes to determine depth. The minimum resolvable water depth is no longer dicta...
