Real time intensity measurement at arbitrarily many spots of symmetric field with a small number of sensors and its application

摘要: 探讨了以少数量的传感器实现实时测量空间对称动态场任意多点场强的方法,结合某蝙蝠发声声场强度分布测量系统的设计,介绍了该方法在此测量系统中的应用,并给出了实验测量结果。结果表明该测量方法与传统测量方法效果相当,且对于瞬态声场的测量,该方法相对于传统阵列法可节省大量传感器,降低成本。

Abstract: This paper makes an inquiry into realizing a method to real time measure wantonly many spot field intensity of space symmetrical dynamic field with a small number of sensors Furthermore describes the application of this method in the bat sound field intensity distribution measurement system combining our practical work.
