WebIonospheric propagation, where radio waves are refracted by ionised layers in the atmosphere. 4. Tropospheric propagation, where transmission is “line of sight” with some atmospheric refraction occurring. 5. Scatter propagation, where natural phenomena such as tropospheric turbulence or ionised meteor trails are used to scatter radio waves. WebWave Gauges. Gauges may be mounted on platforms or on the seafloor in shallow water. Many different types of sensors are used to measure the height of the wave or subsurface pressure which is related to wave-height. Sound, infrared beams, and radio waves can be used to determine the distance from the sensor to the sea surface provided the ...
