Signal Processing in the Sector Scan Indicator

Abstract

The Sector Scan Indicator is known as a device for indicating the position in a sound beam of objects from which sonar echoes are received. The centering of the sound beam on a target submarine and the presentation of the submarine's aspect have appeared to be the principal uses for this equipment. It is now evident that this device is also particularly adapted to the reception of a weak noise signal in a background of ambient noise. In the reception of echoes, SSI has a sensitivity about equal to that of the ear. However, electronic treatment of the output to extract remaining information offers promise of further improvement.
