A new blind anti‐jamming algorithm based on a novel antenna array design

The next-generation navigation tools are developed to enable precision and reliability. Military users more likely encounter jamming, so it is necessary seek the technologies which can steadily provide high-precision positioning services in all-weather harsh conditions. However, when use an array antenna for interference suppression, usually introduces pseudorange carrier phase biases, deteriorates accuracy integrity of positioning. To address this issue, authors propose a blind anti-interference algorithm with biases suppression. Compared commonly used space–time adaptive anti-jamming algorithms, not only retain advantages simple structure but also suppress both crucial obtain availability Moreover, proposed be applied easily quickly actual system minor hardware changes some cases. relevant theoretical analysis experiments have proved effectiveness algorithm: (1) code almost ignored (2) significantly improve positioning; average error 1.6 mm, keep better than 0.1 m 97.5% time.
