Abstract :
It is already well-known that wind variability plays a key and crucial role in pollutant transportation and climate change. The impact of wind variability is not only on air but also on sea activities because it can cause turbulence and water warming. Hence, it is necessary to have specific and sophisticated instrumentation capable of monitoring local and wide range of wind. One of the most important instrumentation dedicated to wind monitoring is wind profiler that can work in coupled manner with a RASS (Radio Acoustic Sounding System). This paper presents a preliminary study to process signal from a wind profiler in order to detect echoes due to presence of obstacle along to emitted wave path. The scope is to discriminate echoes to obtain the true values of wind, thus, the correct wind profile.
