Web4.2. Chebyshev array design The main goal is to approximate the desired AF with a Chebyshev polynomial such that • the side-lobe level meets the requirements, and • the main beam width is as small as possible. An array of N elements has an AF approximated with a Chebyshev polynomial of order m, which is m N= − 1.
