| 摘 要： | 本文研究了高频寻常波在均匀等离子体中垂直均匀背景磁场传播时,由于在传播方向上有限区域内存在等幅密度扰动驻波引起共振折反射的理论.认为这种共振反射理论可能解释ESF条件下VHF/UHF雷达强散射和卫星与地面通讯中断等现象.

| Abstract: | In this paper, resonant reflection of the ordinary wave propagating perpendicular to background magnetic field by periodic standing wave of plasma density is studied. The resonant reflection mechanism is able to explain strong scattering of VHF/UHF radar in ESF conditions. |
