Measurements and parameter estimation of clear air and sea echoes in MST radars

Wind profiling is a rather recent application of Doppler radars to atmospheric sounding. Wind profilers provide information on wind speed and on turbulence at different heights by means of analysis of clear air echoes. When a wind profiler is installed near the sea, clutter due to echoes backscattered by the sea surface is also received, which can heavily affect measurements. In the present work, we discuss a parameter estimation technique which can be used to deal with this problem. We also show some results of its application to data measured by an MST radar installed at King George´s Island, Antarctica, where both atmospheric and ocean echoes are present. The processing capabilities needed to implement this technique can be obtained from a PC connected to the measurement system
