Abstract : The objective of the program was to test the Pictorial Sonar technique, which employs wide-band sound projection and data processing of target echo returns received on two hydrophones to form the equivalent of a large number of high resolution beams. The program demonstrated the feasibility of the Pictorial Sonar principle for detecting and locating isolated target returns provided that only a small number of angle resolution elements are filled simultaneously. The report describes the Demonstration Model and the tests performed. The experimental results are presented and shown to correspond with the results predicted by the analytic model. A new configuration, which should result in improved Pictorial Sonar performance in a multiple target situation, is presented. (Author)
