Research and Simulation on Wide Nulling of Fuze Antenna Beamforming
In the encounter course of the missile and target, the alteration of the jamming is very rapid. So the nulling of fuze antenna beamorming system must aim at the jamming rapidly. But the nulling width of the conventional beamforming algorithm is very narrow. Because of the restriction of the processing speed and the real-time requirement of the whole beamforming system, the jamming may move out of the beam nulling during the period of the weight processing, which will affect the anti-jamming performance of the algorithm. A broadening null algorithm of the fuze antenna beamforming is researched in this paper. The nulling is broadened through rotating the steering vector and numerical treating to the covariance matrix. The robustness of the fuze antenna beamforming is raised through adopting this algorithm. The results of computer simulation verify the efficiency of the proposed method and showed that the nulling is wide enough when the jamming move quickly.
