Wideband array processing with constant beam pattern beyond the spatial sampling limit Conference Paper uri icon

abstract

  • This paper first addresses the Direction of Arrival (DOA) ambiguity problem in Uniform Linear Arrays (ULAs) and then proposes a wideband implementation through narrowband operation for an aliased array. It is shown that by an appropriate design e.g., frequency band selection and separation, signal spectrum support, and multiples access, one can resolve the aliasing, while maintaining larger array element spacing. A frequency invariant beamformer is used to control a contact bandwidth among the frequency subbands. The algorithm takes an all-angle approach for DOA and transmitted data signal estimation. Finally, the stability of the methodology is justified and the collaborated by simulation results. 2009 SPIE.
