Abstract
In this paper, we propose a new beamforming scheme for pulse-based signals, particularly, for ultra wideband pulses, by employing a random array geometry and an orientation matching of the arrays. Unlike conventional directional beamforming, the introduced scheme forms an array beam, being independent of a signal impinging direction for both near-fields and far-fields. As a consequence, it is advantageous to suppress unwanted interferences having same frequency contents and coexisting in the same arrival direction with reference to the desired signal. The proposed beamforming concept is analyzed together with the definitions of the −3dB beamwidth and restlobe level. Besides, the orientational beampatterns are compared with the directional beampatterns, and observed that the array responses are different according to the respective spatial processing domains.
