Field tests of a Thorn EMI acoustic camera used in an underwater acoustic television system
Abstract
A very large number of pictures were registered on videotape. The subjective impression of an acoustic image was judged to be as important as quantitative analysis of such features as: target detectability, range of the system, resolution, detectable target contrasts as seen by the camera, etc. Although laboratory conditions did not exist at the test site a number of interesting conclusions were derived from the picture tapes and are discussed. The Thorn-EMI Technical Specification for the system is fulfilled.
