Abstract
A new method for the design of adaptive array processors based on semi-infinite quadratic optimisation techniques is presented. The method is to minimise array output power subject to linear functional inequality constraints. Various errors and mismatches between ideal cases and actual scenario are incorporated into the constraints, which set the allowable upper and lower bounds on the array response to the desired signal within the prescribed error ranges; thus, the resulting processors are robust. Computer simulations and comparisons with Frost's processors are given to show the performances. The new method can also easily be extended to the design of broadband array processors with errors and mismatches.
