Abstract
A new method is proposed for broadband beamforming of two-dimensional (2D) spatio-temporal (ST) bandpass plane waves (PWs) using a complex 2D FIR filter structure having a trapezoidal-shaped passband at baseband and achieves the minimum possible temporal sampling rate for a given bandwidth. Experimental results show that this method is capable of enhancing 2D broadband bandpass ST PWs according to their directions of arrival (DOAs) in the presence of severe co-channel interference
