摘要
空间电磁波干扰和电源高频谐波干扰是分量核旋仪观测系统的主要干扰源;分量核旋仪观测系统的探头、分量线圈、供电系统及通信线路是主要的干扰途径。作者着重对干扰途径进行了分析,提出了观测系统的抗干扰措施,并分别对探头及信号输入通道、分量线圈、供电系统、通信线路、仪器电路、仪器控制软件进行了全方位的抗干扰设计,新设计提高了分量核旋观测系统的抗干扰能力。
The spatial electro-magnetic disturbance and the high-frequency harmonic jamming from the power supply are the major disturbance sources to the component nuclear precession magnetometer. The sensor, coil, power supply system and communication lines are the main disturbed routes. We emphatically analyze the disturbance routes and provided the anti-jamming measures to the observation system. The anti-jamming designs have been made to the sensor, input channel, component coil, supply system, communication lines, circuit and controlling software, which have improved the anti-jamming capacity of the observation system.
