Sidelobe performance in quadratic phase conformal arrays

Sidelobe performance in an array with a quadratic phase distribution is related to the array curvature. Conditions are derived that ensure well-behaved sidelobes for quadratic phase conformal arrays. A similar condition is derived for parabolic shaped arrays and results are given to illustrate the validity of the derived requirement for well-behaved sidelobes for both parabolic and circular arrays. In addition, the sidelobe performance of a nonuniformly spaced linear array is related to the curvature of an equivalent conformal array
