An Anti-Jam Manpack Antenna for Global Positioning System Application
Abstract
The GPS Anti-Jam Manpack Antenna (AJMA) system is an ECCM addition to the GPS manpack/vehicular user equipment which will minimize GPS receiver performance degradation due to a jammer by steering a null into the direction of the interference source. Operating strictly at the GPS RF signal level AJMA will easily interface with a GPS receiver without modification and add minimal signal degradation. From results of the experiments described, it is concluded that there exists a feasible method of using null-steering antenna systems to counter CW jammer threats. A number of AJMA configurations were applied successfully and tested practically. (Author)
