This
paper proposes a design of an adaptive beamformer for arbitrarily Uniformly
spaced Linear Array (ULA) antennas.
Least
Mean Square (LMS), a prevalent adaptive beamforming algorithm, has been
employed in the beamformer for the ULA antennas.
A
procedure has been introduced to validate the proposed design.
Applying
the proposal, a LMS based adaptive beamformer for 8×1 ULA antennas has been
built and implemented on Xilinx FPGA.
The
fundamental characteristics of the implemented beamformer have been measured
and verified.
The
experimental results show that the beamformer is capable of creating
appropriate weights in order to steer the main lobe of the ULA antennas to the
desired direction and to place simultaneo usly null points towards the
interferences in case of NOAA LEO satellites system.

| Abstract: | This paper proposes a design of an adaptive beamformer for arbitrarily Uniformly spaced Linear Array (ULA) antennas. Least Mean Square (LMS), a prevalent adaptive beamforming algorithm, has been employed in the beamformer for the ULA antennas. A procedure has been introduced to validate the proposed design. Applying the proposal, a LMS based adaptive beamformer for 8×1 ULA antennas has been built and implemented on Xilinx FPGA. The fundamental characteristics of the implemented beamformer have been measured and verified. The experimental results show that the beamformer is capable of creating appropriate weights in order to steer the main lobe of the ULA antennas to the desired direction and to place simultaneo usly null points towards the interferences in case of NOAA LEO satellites system. |
