Anti-jamming space-time processor with digital beamformer for satellite navigation

Abstract

This paper presents a novel space-time adaptive processor with digital beam forming algorithm based on least mean squares (LMS) method. Furthermore, the omnidirectional optimization principle for the algorithm applied in satellite navigation field is introduced. The algorithm minimizes the deviation of the radiation pattern due to the edge effect of asymmetric substrate in the miniaturization design of antennas. The anti-jamming performance of the introduced algorithm is verified through the experiment of radiation pattern, satellite signal receiving experiment and anti-jamming experiment.
