【摘要】 分析表明，在半航空频率域测量中，感应式磁传感器作为接收系统的重要组成部分，对探测结果有着巨大的影响，当前还没有应用于该领域的商用空心线圈传感器。针对这种问题，设计了一款应用于该领域的空心线圈传感器。通过电磁分析及计算软件对空心线圈进行了建模分析，仿真了频域特性，根据结果及项目要求设计了线圈参数。为降低系统噪声，采用双极性晶体管为核心设计了放大电路，并在磁屏蔽桶中测量了噪声水平。同时通过无人机搭载进行实际测试，验证了设计成果符合要求。更多还原

【Abstract】 In semi-airborne frequency domain measurement, inductive magnetic sensor, as an important part of the receiving system, has a great influence on the detection results. Currently, there is no commercial hollow coil sensor applied in this field. To solve this problem, anair-core coil sensor is designed for this field. The air-core coil is modeled and analyzed by electromagnetic analysis and calculation software, the frequency domain characteristics are simulated, and the coil parameters are designed according to the results and project requirements. In order to reduce the noise of the system, the amplifier circuit is designed with bipolar transistor as the core, and the noise level is measured in the magnetic shield barrel. At the same time, the actual test carried out by UAV verifies that the design results meet the requirements.更多还原
