Abstract
In order to make the global navigation satellite system (GNSS) have the ability of anti-jamming, it is a feasible scheme to replace the antenna in situ. However, the widely developed anti-jamming antenna is bulky and heavy, which can not meet the needs of direct modification, especially when the space is limited, such as airborne. We design and test an anti-jamming satellite navigation antennas system, which is based on the recent LTCC technology to lose its weight and reduce the cubage. At the same time, a real-time and high-performance DSP is adopted to realize the spatial-temporal filtering algorithm. For anti-jamming, this algorithm, which uses the LCMV, is well enough. An experiment with this anti-jamming antenna system has been carried out to prove the antenna can not only resist single or multiple interferences, but also achieve the anti-jamming performance of the existing anti-jamming antenna. More importantly, the minimum weight can be close to 600g, and the volume can meet the requirements of directly replacing the existing airborne GNSS antenna.
