Abstract

The system has wide-angle coverage or even omnicoverage while at the same time has high gain by use of this technique. The angular coverage required is obtained by a number of overlapping narrow high-gain beams. The output of each of the high-gain beams is amplified and passed through a threshold device. The effect of the threshold device is to attenuate all noise sources in all beams which do not have a signal. The beam which receives the signal having high gain presents a high signal-to-noise and necessarily high signal level to the threshold device. The outputs of all the parallel threshold devices are then summed. The overall effect is to produce a signal-to-noise which is equivalent to that received by a high-gain antenna while at the same time having omni-coverage.
