A Core Memory Display for Sonars.
Abstract
The capabilities of contemporary pulsed sonar displays are severely restricted by the characteristics of the materials used to create target persistence. This report describes the application of a novel technique to improve the fidelity with which sonar signals can be displayed to the operator. The function of temporary signal retention, normally provided by long-persistence phosphor, is accomplished instead with a digital core memory unit. The pulsating appearance of conventional displays has been removed, and an increased dynamic range of displayed signal intensities has been achieved. The storage method will permit a number of signal processing techniques to be studied with this versatile, general purpose, experimental display. (Author)
