Abstract

This paper addresses the issue of beampattern synthesis with flexible magnitude response and low sidelobe in a frequency diverse array radar. It is formulated as an optimization problem in terms of ℓ1-norm minimization, which encourages the sparsity of array pattern. An ℓ1 iterative phase compensation (IPC) technique is employed to transform the nonconvex constraint to phase compensation form. Then, to further reduce the sidelobe level, a reweighted ℓ1-IPC algorithm is devised, in which a sparsity-enhanced scheme is utilized to convert the ℓ1-norm to a new cost function that more closely resembles ℓ1-norm. Numerical results are presented to demonstrate the effectiveness of the proposed approach in different scenarios.
