摘　　要：根据冰层厚度探测的实际需要,研究了频率域电磁法的冰层厚度探测系统.系统是利用频率域电磁法的基本原理设计,同时,利用椭圆率来消除一次场的影响,可实现一次和二次磁场的分离提取、数据采集等模块功能.并且在实验室对传感器的电流发射部分和数据接收部分进行了试验,与理论数据进行比对.实验结果表明,系统可实现冰层厚度检测和生消变化过程检测.According to Engineering requirement of winter ice thickness measurement, a ice thickness automatic thickness measurement system is designed. This system is a ice thickness sensor using frequency domain electromagnetic principle.It realizes functions of an electromagnetic field, the two electromagnetic separation, data acquisition and so on. At the same time, This system put forward eliminate the influence of primary field by using ellipticity. Experimental testing is done about current emission and data receiving part. The experimental results show the detection system can achieve the effect on the ice thickness and dissipation change detection according to the theoretical calculation data analysis.
