Abstract

A 3-D forward look sonar system has been developed and built using the concepts described in the papers presented at the 5th International Symposium on Unmanned Untethered Submersibles [J.M. Cuschieri] and at Ocean 91 [Cuschieri and Ping]. The two main features of this sonar system are the generation of truly 3-D images and the use of continuous random projector signal. Having built the transducer hardware and a developed a method by which the random signal is generated and delayed for the electronic scanning, the first images were collected in a fresh water test tank. The initial images were rather poor due to poor energy distribution within the bandwidth of the projected signal. Modifications in the way the signal is generated have been implemented. Images were again collected in the fresh water test tank and the enhancements to the images documented
