Adaptive null-steered interference-rejection for a mobile satellite receiver
One of the most useful applications of antenna arrays is interference rejection. This paper describes an antenna array that was designed for the sole purpose of rejecting interference of a satellite receiver from a close-proximity jamming source. Since this jammer can move relative the satellite antenna, the antenna array must adaptively adjust its null direction accordingly. The system consists of a six-element array of circular fractal patch antennas in conjunction with a receiver channel that is dedicated to interference detection and tracking.
