This paper derives two novel frequency invariant beamformers (FIBs) for use with wideband synthetic aperture channel sounders. Results using measured data show that the choice of beampattern can affect the amount of diffuse multipath energy received through the array sidelobes and influence the estimated channel impulse and frequency responses.
