Abstract

Described herein are systems, methods, and other techniques for localizing an interference signal relative to a GNSS receiver. A method includes collecting a first phase difference measurement using first and second antennas and a first angle measurement using an inertial sensor. The method includes collecting a second phase difference measurement using the first and second antennas and a second angle measurement using the inertial sensor. The method includes searching a phase difference map using the first and second phase difference measurements and an angle offset between the first and second angle measurements to identify a compatible set of phase differences in the phase difference map. The angle of arrival of the interference signal is estimated based on indices of the compatible set of phase differences in the phase difference map.
