Comments on Minimum Sidelobe Configurations

M.A. Holdaway

May 7, 1997

Keywords: array configuration, ring arrays, filled arrays, sidelobes

L.R. Kogan's (1997) minimum sidelobe configurations are discussed in the framework of the debate between ring-like and filled array configurations for the MMA. If multiple configuration imaging will be standard for the MMA, we predict the filled, minimum sidelobe configurations will result in superior imaging of complex objects. If single configuration imaging will be standard for the MMA, simulations have shown that ring-like configurations will result in superior imaging of complex objects. Therefore, a strategy for the use of the configurations (ie, predominantly multiple configuration imaging or single configuration imaging) must be developed.
