摘　　要：针对常规的波束设计方法应用到实际任意形状阵列时不能有效获得期望最佳波束图,提出了一种基于模拟退火算法的任意形状传感器阵列多波束优化反演设计方法,实现了任意形状传感器阵列多波束的设计。通过改进波束优化反演的目标模型有效实现了波束优化,基于实际阵列模型的设计思想有效克服了因阵列模型失配带来的影响。方法具有宽容性、灵活性,为任意阵特定形状波束的设计提供了一种新思路,对于实际多传感器系统的多波束设计具有重要意义。As the conventional method of array pattern synthesis can＇t always converge to the desired optimum beam pattern for arbitrary geometry sensor arrays in engineering applications,this paper presents an efficient inverse method on array pattern synthesis using simulated annealing,which can be used in beam pattern design for arbitrary geometry sensor arrays.The method optimizes the beam pattern by improving on the model of target function properly.The design thought based on measured array manifold overcomes the influence brought by the mismatch errors between actual array model and ideal array model greatly.The practical application results indicate that the proposed optimum beam pattern design method is tolerant,feasible and effective.The method proposed develops a brand new scheme for given shape beam pattern about arbitrary geometry sensor arrays and can provide a significant reference on beam pattern design for the actual multi-sensor system.
