Abstract :
The element to beamspace transformation property of an overmoded coaxial beamformer is a unique feature in radio direction finding applications. The transformation reconfigures the coaxial antenna circular receiving aperture into the linear Vandermonde form required for direction of arrival computations whilst still maintaining omnidirectional coverage of the radio environment.
