| 摘 要： | 水下等离子体声源应用越来越广泛,但其电磁辐射脉冲测量却是一个空白和难点;分析了水下等离子体声源的工作特性,论证了电磁辐射脉冲测量设备,根据国家标准及电磁场辐射理论制定了测量方案,建立了水下等离子体声源电磁辐射脉冲测量系统;结合水下等离子体放电实验,对辐射电场和磁场进行了实时测量,并利用Matlab软件对测量数据进行了分析处理,研究了水下等离子体声源电磁辐射脉冲的时域频域特性。测量结果显示,在10μF/16kV电弧放电条件下,触发脉冲辐射的电场强度为45dBV/m、磁场强度为-112dBA/m,放电脉冲辐射的电场强度为35dBV/m、磁场强度为-98dBA/m。与国家标准规定的限值比较,辐射脉冲还未超过限值。
