Bistatic Sensing and Multipath Mitigation with a 109-Element GPS Antenna Array and Digital Beam Steering Receiver

Abstract

NAVSYS Corporation has developed a 109-element GPS antenna array and a modified version of the High-gain Advanced GPS Receiver (HAGR) which can perform beam steering with the digitally-combined signals from each antenna element. If adequate gain can be obtained from reflected GPS signals, applications involving Earth mapping, ocean surface mapping, terrain modeling, digital mapping, and other passive monitoring uses can benefit. Previous research in such uses of reflected GPS has been done at NAVSYS with a 16-element antenna array to sense the reflected signal. This paper describes the design of a 109-element Digital Beam-Steered Antenna Array and the collection of a data set to test the concept of operation.
