| Abstract: | The application of the nonlinearly constrained optimization method to low sidelobe synthesis of the space-scanned axial dipole arrays on cylindrical surfaces is discussed inthis paper.By adopting the information of the array element realized gain patterns, we propose an approximation method for finding the maximal sidelobe level of the scanned pattern with the prespecified beam pointing, and formulate the synthesis problem of the scanned arrays with the specified scan angle as nonlinearly constrained optimization problems. By using the new direct method, we can find a set of array coefficients that yield a scanned pattern, with the specified scan angle, meeting the specified sidelobe level and maximizing the directivity, if such a set of array coefficients exists.When the sidelobe specification can not be met, we can find a set of array coefficients that yield a scanned pattern meeting the best attainable sidelobe level and maximizing the directivity. Also,some numerical results for the low sidelobe control of the space-scanned axial dipole arrays on cylindrical surfaces are given. |
