ABSTRACT:
A sonar signal processing and display system is described which converts log return data to digital form for storage in a magnetic core memory, from which the data can be reconstituted as analog video signals for CRT display at a higher frame rate. Described are means for comparing new data to old to select updating data for the memory, and means for effecting CRT display of moving target tracks in a color distinct from stationary background returns.
