Abstract

See full text

A method and apparatus for providing a standalone anti jamming (AJ) nuller-beamformer. Signals from an antenna array include a sum of Global Navigation Satellite System (GNSS) signals and jamming signals from a plurality of spatial sources. A front end is configured to amplify, filter, down-convert, and sample the input signals which are then filtered, down-converted, and decimated prior to frequency-domain and time-domain partitioning. Weights are computed and applied for spatial nulling of jamming signals in each frequency bin for the partitioned signals. Frequency and time-domain reconstruction generates a reconstructed signal with suppressed jamming.
