Beamforming of Broadband Bandpass Signals using Multidimensional FIR Filters
[article]
2012
Two new discrete-domain methods are proposed for the beamforming of two-dimensional temporally broadband bandpass plane waves using two-dimensional spatio-temporal finite impulse response filters with novel trapezoidal-shaped passbands. The first method employs a complex-coefficient two-dimensional finite impulse response filter structure having an asymmetric trapezoidal-shaped passband at baseband and achieves the minimum possible temporal sampling rate for a given temporal bandwidth.
