Abstract A fast iterative optimization algorithm for sum and difference patterns with controllable accuracy and range of angle measurement is proposed, which can be used in fast targets location under wide angle coverage and accurate angle tracking of maneuvering targets. Under expected accuracy or range of angle estimation, the expected main-lobe of sum and difference patterns are modified in the form of sinc function and its derivative respectively, then the sum and difference patterns are rapidly synthesized with the proposed regional weighting pattern synthesis algorithm in the close form. The proposed iterative optimization algorithm can effectively maximize the range of effective angle measurement at a given input signal to noise ratio and angular accuracy, or get optimal accuracy within a given range of angle measurement.
