N2 - This paper presents an adaptive beamformer for smart antennas, which is able to steer its main beam and nulls in azimuth over a wide frequency band, without tape delay lines or frequency filters. This is achieved based on fully spatial signal processing techniques wherein a two-dimensional antenna array operates as a spatial filter, processing the received signals with only weighting schemes. Previous weighting schemes algorithms are not capable of working properly in a noisy environment. However, in this paper, a second order Kalman filter is employed to efficiently synthesize the radiation patterns in a noisy environment.
