A novel blind multi-target beam-forming algorithm in guidance data link system

This paper proposes a novel blind multi-target beam-forming algorithm to perform a multi-target beam-former for guidance data link system. The proposed algorithm exploits the knowledge of the pseudo-noise (PN) code used in data-link communication system to generate the transmitted command as reference signal. A novel approach, which a band-pass filter is used, is adopted to improve anti-jamming performance in environment with strong interference. Simulation results demonstrate that our proposal can achieve a superior anti-jamming performance than Multi-target Least Square Constant Modulus Algorithm(MT-LSCMA) in environment with strong jamming.
