Dolph- Chebyshev becomes a Binomial array when there are no side lobes.

A. True

B. False

I got this question in a job interview.

This intriguing question comes from Binomial Array topic in section Phased, Adaptive and Binomial Arrays of Antennas

The correct option is A. True

The explanation is: Binomial array is used to synthesize patterns without side lobes. Dolph- chebyshev method is used to design array with desired side lobes. When the side lobe of the Dolph drops to -∞ dB, it behaves like a binomial array.
