Data processing for high-resolution active sonar

Active sonars which have high resolution in range and angular sector generate large volumes of data which must be interpreted by the sonar operator. Often the magnitude of the data volume greatly exceeds the capabilities of both modern display technology and the human element. This paper discusses the use of computer-assisted data evaluation and display techniques which address this data mapping/reduction problem. The importance of simulation and real data analysis in studying this problem is explained. Results of a typical simulation are given to show the impact of various performance and computer loading parameters.
