The SODAR advantage
Short SODAR functional description
A SODAR emits sound pulses into the atmosphere. The sound pulses are
reflected at temperature inhomogeneities in the air. The temperature inhomogeneities move with the wind, which result in frequency changes (Doppler Effect)
between emitted and received sound pulses. The SODAR antenna receives the
echoes and they are analysed. The result is stored, processed, and presented.
A SODAR measurement in at least three directions provides a three-dimensional
wind profile.
Doppler Effect
Imagine standing on a street and
listening to an ambulance siren. When
it is driving towards you the sirens will
have a certain frequency. When it has
passed the frequency has changed.
This physical phenomenon is called
“Doppler Effect” or “Doppler Shift” and
is widely used in a variety of different
situations for remote sensing speed
and direction. Some examples are
submarines, meteorology, aviation,
medical imaging, flow measurement
and astronomy.

Phased Array SODAR
Scintec SODAR
Traditional SODARs utilize only three
transducers. This makes them very sensitive to individual directional errors. Traditional SODARs also have to be carefully
calibrated.
Phased array is a stationary flat cluster
with many small transducers. The directions are created with short delays of rows
and columns which result in a certain
emission angle (Huygens principle). The
emission angles can be adjusted.
WindCollector2 is equipped with a
Scintec SODAR SFAS.
The Scintec SFAS is an phased array
SODAR with modern multi-direction
and multi-frequency technology. In
comparison with measuring masts, the
Scintec Sodar SFAS has shown that it
is a better choice. Compared to other
SODAR brands the SODARs from
Scintec provide the best results.

A truly mobile integrated SODAR
High quality
Modular
WindCollector2 is a truly mobile wind measurement system,
completed with a superior SODAR and a high quality mobile
power solution. All components are carefully selected to
give you the highest durability, flexibility, and the best
measurement results.
WindCollector2 is a stand-alone system which makes it very
flexible to transport and handle.
Compact
WindCollector2 has a very small footprint and low weight,
which makes it the smallest integrated Sodar system in the
world.
User friendly
Easy to install. Easy to use. Easy data transfer. Easy to
maintain.
High Security
The trailer is removed from the measuring site, leaving the
WindCollector2 protected against theft. The electronic
control system, the alarm systems, and the wind measurement can be accessed remotely. An automatic fire extinguisher system is optional.
Superior technology
The built-in Scintec Sodar SFAS consists of 64 transducers
and utilizes a multi-band technique with 10 frequencies in 9
directions. The signal pulses used give you a true 5 m
resolution. The frequency range is 2525 – 4850 Hz.
For all climates
Thanks to the inverted horn design
with antenna heating, Scintec Sodar
SFAS works in virtually all weather
conditions.
The Phased-Array technology makes
the measurement totally temperature
independent.
making wind measurement easy!
Scintec APRun, a Multi-role Software
Included
In the field-PC, Scintec APRun is used for controlling the
sodar, data collection and Self-tests. In your office-PC,
Scintec APRun is used for data analysis, presentation,
preparation for reports and reprocessing data. APRun also
has built-in Web interface, alarm events, timer events, and
more.
• Scintec Sodar SFAS with antenna heating
Wind Data
A complete set of wind parameters are measured on all
selected heights and are stored in the RAW-files. ASCII-text
files are created automatically in the field-PC with a selected set of parameters. This makes it easier when using the
data in other software. These files can be re-created
anytime in the future from the RAW-files. Exported data in
row format is compatible with WindPro.

No need for temperature measurement
Scintec SODAR SFAS is less sensitive to levelling errors
than a traditional SODAR. With the phased array technology the emission angles are created in the software, using
Huygens principle. When the SODAR is emitting in one
main angle (24°) it also emits in one mirrored angle (19°)
and data is collected from both directions simultaneously.
Phased array SODARs don’t rely on an additional
temperature measurement thanks to varying emission
angles.
