讨论了地面设施在150-700 kHz频率范围内观测到的无线电波的产生理论。这项工作是早期讨论的延续（Wu等人，1989年），其中提出，被捕获的电子沿着极光场线可以导致回旋不稳定性，这放大了在地面上观察到的哨声波。本研究的目的是调查波放大的传播效果，并检查所提出的机制是否确实可行。
A theory of generation of radio waves observed by ground-based facilities in the frequency range 150-700 kHz is discussed. This work is a continuation of an earlier discussion (Wu et al., 1989) in which it was proposed that the trapped electrons along the auroral field lines can lead to a cyclotron instability which amplifies the whistler waves observed at ground level. The objective of the present study is to investigate the propagation effect on the wave amplification and to examine whether the proposed mechanism is indeed viable.
