The purpose of this proposed effort is to provide a design for a new generation of GPS CRPA which will have superior anti-jam performance against a large number of intentional interfering sources than is currently possible. At the same time, this new antenna (including electronics) will be designed for a small aperture, have reduced Radar Cross Section and minimum cost in commercial production quantities. This proposal demonstrates an in-depth understanding of the GPS system as it relates and responds to jamming and interference signals, and will highlight experience in antenna design, measurement and fabrication. MRC, allied with Compton Research, Inc., provides a unique capability to analyze, design, and in later phases, fabricate and measure new integrated GPS hardware. MRC is well known for its special purpose antenna design and fabrication, but MRC has also designed, built and tested large scale integrated electronics which in one instance is a GPS antijam filter. This effort is proposed to investigate antenna configurations given the satellite, GPS receiver and interfering signal spatial envelopes. An array of designs and cost tradeoffs will be delivered.
