Abstract :
In this paper, the beamspace approach for designing a broadband antenna array beamformer, with frequency invariant characteristics, is devised and implemented with the sliding window linearly constrained RLS algorithm, referred to as the SW-LC-RLS beamforming algorithm, to deal with broadband moving jammers suppression. From computer simulation results, we show that the proposed scheme is more robust against moving jammers compared to other conventional algorithms.
