Null and beam steering performance of rectangular arrays with Dolph-Chebyshev weighting.

摘要

This masters thesis describes the beamforming performance of rectangular arrays with Dolph-Chebyshev weighting. This type of weighting provides optimum mainlobe beamwidth for a fixed sidelobe level. However, the beamwidth of the mainlobe increases when a lower level is selected for the sidelobes. The null/beam steering performance of such an array, which can be used for GPS anti jamming applications, is discussed and the results are presented for linear and rectangular arrays with 4 and 8 elements. The thesis also presents the optimum Minimum Variance Distortionless Response beamformer's performance in presence of interference.
