%X A steering-invariant constant beamwidth beamforming algorithm is proposed. On the basis of main-lobe shape controlling idea, the proposed algorithm uses the main-lobe on some direction as reference main-lobe, and constructs the reference beampattern whose main-lobe direction is changed with different designed main-lobe direction by parallel moving the reference main-lobe, and keeps the height of side-lobe adjusted adaptively. Some virtual interfere sources are set on the look-in domain, the proposed algorithm adjusts the intension of them iteratively and makes the designed main-lobe on arbitrary direction inosculated the reference main-lobe, then the steering-invariant constant beamwidth beampattern is obtained after some iterative calculations. It is shown by simulation that the proposed algorithm can form the steering-invariant constant beamwidth beampattern effectively under the designed main-lobe direction of ±60°.
