Measurements and parameter estimation of clear air and sea echoesin MST radars

摘要

Wind profiling is a rather recent application of Doppler radars toatmospheric sounding. Wind profilers provide information on wind speedand on turbulence at different heights by means of analysis of clear airechoes. When a wind profiler is installed near the sea, clutter due toechoes backscattered by the sea surface is also received, which canheavily affect measurements. In the present work, we discuss a parameterestimation technique which can be used to deal with this problem. Wealso show some results of its application to data measured by an MSTradar installed at King George's Island, Antarctica, where bothatmospheric and ocean echoes are present. The processing capabilitiesneeded to implement this technique can be obtained from a PC connectedto the measurement system
