Abstract

Collision-avoidance devices are all based on the use of either electromagnetic or acoustic waves, although the former (i.e. radar) is of particular interest for this purpose.

After reviewing briefly the fundamental theory which underlies all methods of detecting, locating and recognizing a distant target, reference is made to the successful development, in the Electrical Engineering Department of the University of Birmingham, of a narrow-band sector-scanning sonar system employing a multiplicative array to give improved target resolution. It has been demonstrated experimentally that the same principle can be applied to obtain a sector-scanning radar system capable of scanning rates as high as one million scans per second, which has applications for airfield surveillance radar. Attention is now being directed to the possibility of using wide-band signals, either to improve target detection and location for an array of a given size or to obtain additional information about the nature and behaviour of the radar target itself. Two possible methods of using wide-band signals are described.
