摘要: 机械天线作为超低频通信技术,是当今国际瞩目的一个新兴研究领域,在远距离通信、水下通信等方面具有广泛的应用前景.为实现小型化和低功耗的超低频机械天线,提出旋转偶极子式机械天线结构和通信模型.针对提出的通信拓扑结构及通信信号辐射强度,研制三轴正交线圈作为信号接收单元.提出基于线圈热噪声电压与感应电压比值的灵敏度归一化表征方法.并对研制线圈的灵敏度及工况进行实验.实验结果表明:灵敏度理论模型可用于高灵敏度线圈设计,研制的空芯线圈可用于机械天线信号接收;铁制品的存在对线圈接收性能有影响.该实验研究为超低频机械天线接收线圈的优化设计提供理论参考.

Abstract: As a super-low frequency communication technology,mechanical antenna is a new research field attracting international attention.It has a wide application prospect in long-distance communication and underwater communication.In order to realize the miniaturization and low power consumption of the super-low frequency mechanical antenna,the structure and communication model of the rotating dipole type mechanical antenna are proposed.In view of the proposed communication topology and the radiation intensity of communication signals,a three-axis orthogonal coil is developed as a signal receiving unit.A sensitivity normalized characterization method based on the ratio of thermal noise voltage to induced voltage is proposed.The sensitivity and working condition of the developed coil are tested.The experimental results show that the sensitivity theoretical model can be used in the design of high sensitivity coils and the hollow coil developed can be used in the reception of mechanical antenna signals.The presence of iron products affects the receiving performance of coils.The experimental study provides a theoretical reference for the optimal design of the receiving coil of super-low frequency mechanical antenna.

Key words: mechanical antenna, super-low frequency, communication model, hollow coil, sensitivity, signal receiver
