This mode is very sensitive to the ionospheric Dopplermodulation.
这种模式是非常敏感的电离层多普勒调制。
2
Theory of Stark effect modulation with Doppler broadening is analyzed by the semiclassical theory.
用半经典理论分析了含多勒普加宽的斯塔克效应调制。
3
Ionospheric frequency modulation causes spreading of the surface clutter in Doppler domain which greatly limits the detection performance of HF sky-wave radars.
