Background
The short wave refers to radio waves with the frequency of 3-30 MHz. Short wave length, poor diffraction ability of ground waves propagating along the earth surface, and short effective distance of propagation. When the short wave is propagated in the form of sky wave, the absorption action in the ionized layer is small, which is favorable for the reflection of the ionized layer. The jump distance of 100-4000 km can be obtained through one-time reflection. Several successive reflections through the ionosphere and earth make the propagation more distant. The most common communication mode is an ultra-short wave communication mode except that short wave communication mode, satellite communication mode and convection layer scattering communication mode are used for medium and long distance communication. Therefore, frequency hopping communication stations based on short-wave and ultra-short-wave communication systems have been developed.
