Abstract:
The land warrior has become increasingly dependent on handheld GPS (Global Positioning System) receivers for providing location information in high interference environments for Situation Awareness, etc. on modern battlefield. A solution is to replace thelegacy antenna with a relatively inexpensive smart antenna appliqu¿ to null out the jam. This smart antenna should be a direct replacement for the current antenna, without any change to the receiver, and with minimal consumption of battery power. A jamindicator and interference signal level measurement can be provided with manual activation of antijam operation only when jam is detected. In Phase-I, Wang Electro-Opto Corporation (WEO) successfully demonstrated the feasibility of such an antennaappliqu¿ for GPS L1 band. We propose a Phase-II program to expand the design to cover both L1 and L2 bands. Two approaches will be taken, one using conventional antennas, and the other using WEO's patented miniaturized slow-wave antenna. Brassboardantenna appliqu¿ with jam sensor and indicator with low power-consumption will be developed.
