Abstract :
The anti-jamming performance of adaptive array used in satellite mobile terminal is limited in the wideband jamming plus multipath environment. A new subband adaptive array method based on LS-CMA is proposed, which can eliminate wideband jamming and theirs multipath when degree of freedom is limited. The formula of this method is deduced theoretically. The relationship of subband adaptive processing and signal correlation is also discussed. Simulation results show the validity of the proposed method
