Abstract
Radars based on the Frequency-Modulated Continuous-Wave (FMCW) technique
have proven to be an excellent tool for the Atmospheric Boundary Layer (ABL) stud-
ies. This layer of the atmosphere is of vital importance for the understanding of
weather and climate. FMCW radars provide high sensitivity and high range resolu-
tion needed for observation of small scale turbulence.
This thesis describes the FMCW Wind Pro ler operating at UHF band as of
Spring 2010. At a later stage it will utilize the spaced antenna (SA) technique for
achieving three-dimensional wind elds. This work describes its principles of oper-
ation, the current status of the radar hardware, and comments the new programs
developed for its proper operation. It discusses the sensitivity of the Wind Pro ler
derived from laboratory tests and the results of the eld deployments. The current
design uses four antennas, one for transmission and three for reception. The major
drawback of the Wind Pro ler is the isolation required between the transmitter and
the receiver. A new scheme is proposed to overcome this problem by using Inter-
rupted FMCW. Recommendations for the future hardware development of the radar
and conclusions are provided.
