Maneuver Optimization for Synthetic Aperture based DOA estimation of GNSS Jammers

摘要

GNSS denial via jamming is a low skilled attack which can be performed by nearly anyone using tools which are readily available through the online marketplace. Methods of jammer mitigation such as beamforming or other active methodologies require an estimation of the location of the jamming signal source. There is interest in developing systems which can be used to identify and locate the sources of broadcast signals, either for the purposes of augmenting mitigation or for the purposes of taking direct action to eliminate the sources of jamming signals. One way that such localization systems might be deployed is on rotor-wing aircraft which may be utilized to perform synthetic aperture direction of arrival (SA-DOA). In this contribution we propose a methodology for identifying circular maneuver trajectories which minimize the estimation error of performing SA-DOA using such a platform.
