Embodiment Construction
[0047] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0048] The invention provides an array antenna optimization method for effectively controlling the dynamic range of the excitation amplitude. The invention uses the Fourier transform algorithm to study a fast synthesis method for the array pattern. The core idea of the algorithm is to calculate the Antenna array element excitation, and then use the convex optimization algorithm to calculate and obtain the array element excitation with the characteristics of small excitation amplitude dynamic range corresponding to the radiation performance. In the hybrid optimization method in the present invention, the traditional IFT algorithm is improved and the excitation amplitude constraint condition is added. , in the part of the convex optimization algorithm, the calculation results of the IFT algorithm are fully utilized, thereby avoiding the shortcomi...
