Analysis of synthetic cylindrical array beam-forming in presence of the elements position-error for semi-anechoic chamber evaluation

This paper describes the study of synthetic cylindrical array beam-forming for narrowband signals, under the influence of antenna elements position-error. The required side-lobe level and the physical dimensions of the array are presumed based on the requirements and limitations to evaluate a RF semi-anechoic chamber. Dolph-Chebyshev algorithm is used for beam-forming because of its optimal beam-width for a predefined uniform side-lobe level. Monte-Carlo simulations reveal the sensitivity of the beam-pattern side-lobe level to the elements position-error.
