Abstract
At present, the electromagnetic environment of navigation signals is complex, the anti-jamming performance of GNSS receiver needs to meet higher requirements. At present, there is no systematic method to measure the anti-jamming performance of the receiver, and the dynamic performance is not taken into account. This paper mainly studies the measurement method of anti-jamming performance of GNSS receiver, and analyzes that the anti-jamming performance of GNSS receiver fluctuates with the change of the arrival angle of jamming signal. In view of this, a method of moving vehicle is proposed, that is, the receiver is placed on the vehicle and moves on the closed path with interference source, so that the azimuth angle and elevation angle of the interference signal entering the receiver are wide. In order to quantitatively measure the DOA range of the receiver on different closed paths, the directional coverage index is proposed in this paper. Finally, the three paths of the example are simulated and verified.
