An UHF Frequency-Modulated Continuous Wave Wind Profiler - Development and Initial Results

Abstract

Microwave radars based on the FMCW technique have proven to be an excellent tool for atmospheric boundary layer studies. They provide high sensitivity, high range resolution needed for observation of small scale turbulence, and very small blind range. This thesis describes the ongoing research effort for development of an FMCW wind profiler operating at 915 MHz which at a later stage will utilize spaced antenna (SA) technique for retrieval of 3D winds within the ABL. It discusses in detail the choice of the radar specifications, the hardware development of each of its subsystems, the laboratory tests performed to evaluate their performance, and the results of the first field deployment. Important conclusions and recommendations for the future hardware development of the radar summarize this work.
