Research on Adaptive Antenna Techniques. IV.
Abstract
Adaptive antennas have been under development in various forms during the past two decades or so. Although adaptive antennas have only been used in small numbers thus far, they have proven themselves capable of rejecting jamming signals to an extent that is unprecedented. Most high performance radar and communications systems being designed to work in jamming environments currently incorporate adaptive antennas. The development of spread spectrum techniques simultaneously with adaptive antennas provides a formidable set of technologies for jam resistant systems. These technologies are compatible and are frequently used in the same system. An adaptive antenna is relied upon to attenuate strong jamming signals as they appear at the receiver 'front end.' Spread spectrum techniques are used to neutralize large numbers of weak jammers that may not be eliminated totally by the adaptive antenna.
