A new iterative phase correction algorithm in conformal antenna array designing

Compared with ordinary linear antenna arrays or planar antenna arrays, space conformal antenna array has many advantages, such as the flexibility and accuracy of the beam. However, conventional algorithms cannot be applied to the designing of conformal antenna arrays, so the weighted minimum mean square error algorithm is proposed. In this paper, a new iterative phase correction algorithm is presented to improve the weighted minimum mean square error (MMSE) algorithm. By using the new algorithm, the shape of the beam can be controlled more flexibly, and more interferences can be resisted compared with the weighted minimum mean square error algorithm. The simulation results show an improved performance in beamforming.
