摘要
针对复杂换能器阵列解析方法求解指向性较为困难的问题,提出一种基于MATLAB的三维指向性图快速确定定向面,以定向面内的二维指向性图确定指向性关键性能参数的求解方法,从而避免了复杂的解析求解过程,克服了解析方法无法求解时需制作换能器实物阵进行测试的难题。这种方法对于缩短产品研发周期、降低研发成本与研究难度具有实际意义。
Based on MATLAB, a method which can determine the directional planes fleetly using three--dlmensional directivity diagrams is proposed. This method avoids the complicated analytical solving procedure and overcomes the difficulty of fabricating actual transducer array for testing the parameters when the directivity can not be gained by analytic solving methods. And it is significant for shortening the research ＆ development cycle and reducing the cost and research difficulty.
