平流层舒曼共振探测器的设计与性能
The design and the performance of stratospheric mission in the search for the Schumann resonances
摘要:
介绍了一个气球平流层飞行任务的技术细节,该任务的目的是测量舒曼共振。座舱是专为测量极低频(极低频电磁波)现象的微弱效应而设计的。样机达到了设计要求。ELF测量系统在整个任务中正常工作;但是,考虑到地面测量而选择的信号放大水平太高。吊舱在地球磁场中的运动在天线中感应出信号,使测量系统饱和。在规划今后的特派团时将考虑到这一影响。实验期间收集了大量遥测数据集,目前正在处理中。有效载荷还包括生物材料以及在极端条件下经过测试的电子设备。
英文摘要:
The technical details of a balloon stratospheric mission that is aimed at measuring the Schumann resonances are described. The gondola is designed specifically for the measuring of faint effects of ELF (Extremely Low Frequency electromagnetic waves) phenomena. The prototype met the design requirements. The ELF measuring system worked properly for entire mission; however, the level of signal amplification that was chosen taking into account ground-level measurements was too high. Movement of the gondola in the Earth magnetic field induced the signal in the antenna that saturated the measuring system. This effect will be taken into account in the planning of future missions. A large telemetry dataset was gathered during the experiment and is currently under processing. The payload consists also of biological material as well as electronic equipment that was tested under extreme conditions.
