An Outfield Test Method for the GNSS Anti-jamming Antenna Pattern

摘要

The outfield test performance of the GNSS anti-jamming antenna is usually far from the theoretical simulation performance. The antenna patter is an ideal tool for evaluating the performance of GNSS anti-jamming antenna. In this paper, the outfield test method of the GNSS anti-jamming antenna pattern was studied. First of all, this paper introduced the common algorithms running in the anti-jamming antenna. The pattern of the anti-jamming antenna is simulated by using the spatial filtering algorithm. Then, an outfield test method of anti jamming antenna pattern is proposed. Finally, the effectiveness of the method is verified by outfield test.
