What does a Dolph-Tchebyscheff distribution achieve?
Answer: C
The Chebyshev distribution gives all side lobes at the same chosen height and, for that height, the narrowest possible main beam, which makes it optimal in a precise sense. Choosing a very low side lobe level approaches the binomial case and a very high one approaches uniform. Equal amplitudes describe the uniform distribution, and bandwidth is governed by the elements and the feed rather than by the taper.
