Abstract
Spatial processing methods that utilize an array of antennas can be used to detect spoofing signals e.g. due to their typical, common spatial origin. A multi-antenna snapshot receiver that utilizes multi-channel processing is used to estimate the beamforming steering vector to each acquired satellite in a constellation. A detector based on steering vector correlation is presented, analyzed and tested. The detection performance is evaluated using a laboratory setup for spoofing, whereas the false detection rate is evaluated using an open-sky recording with an antenna array. The detector has shown good performance to detect spoofing signals in these controlled spoofing scenarios.
