基于仿真退火算法的任意阵列宽带波束形成

提出了基于仿真退火算法优化思想的任意宽带波束设计方法,其期望响应由工作频带划分成的等间隔窄子带上旁瓣波束形成权系数构成。各个子带上的低旁瓣波束则采用基于仿真退火波束形成原理的波束优化设计方法得到。借助计算机对二十四元圆阵进行波束优化设计。结果表明,使用上述方法设计的波束与常规方法相比,获得了更低的旁瓣级和更稳定束宽,充分说明了方法的可行性和有效性。

Design of Broadband Beam Forming for Arbitrary Geometry Arrays Using Simulated Annealing

A new method of broadband beam forming for arbitrary geometry arrays using Simulated Annealing is proposed in this paper.The design requirements of this method were specified by the weights which formed the low-side lobe beams of each sub-band over the broad frequency band.The low-side lobe beams of each sub-band were designed using the optimized beam synthesis approach based on the Simulated Annealing.The beam forming on the 24-element array is optimized.The lower side lobe is obtained with the appropriate...
