Description: The conventional magnitude constraints beamformer is a non-convex issue which is reformulated as a
linear programming issue. A robust beamformer with Phase response Fixed and Magnitude response Constraint
(PFMC) is proposed for Uniform Linear Array (ULA). Making use of the property that there is only a phase factor
difference between the transfer function of the inverse sequence of the weight vector and the array response
function, the phase response is set to be linear and the real magnitude response is constrained. Thus, a convex
optimization cost function is established whose optimal solution can be found out by highly efficient interior point
method.
