REMTECH is a company with offices in France and the U.S.A. which manufactures and maintains the REMTECH DOPPLER SODAR, the R.A.S.S. (Radio Acoustic Sounding System) and the DOPPLER SONAR.

Our DOPPLER SODAR systems measure remotely a vertical profile of wind speed, direction, thermal stratification and turbulence parameters (sigma W, sigma Theta) up to 5,000 meters or more above ground.

They are ideally suited for airport safety (wind shear detection), for air pollution control and forecast, site surveys (power plants) and study of telecommunication network disturbances due to atmospheric conditions.

Meteorological and aeronautical services are interested in the SODARS for the detection
of windshear at airports, and military organizations are, or will be, using the SODAR in programs for weapons development, parachuting, landing on aircraft carriers as well as
flight tests in general.

Our R.A.S.S. (Radio Acoustic Sounding System) remotely measures temperature profiles in the atmosphere with resolution to 0.2^o Celsius.  It can be used in environmental studies for temperature gradients, and for monitoring how the propagation of radio waves is modified by atmospheric conditions.  It comes as an option to our most powerful sodars and can provide measurements up to 1,500 meters above ground.

Recently REMTECH introduced an advanced DOPPLER SONAR system for measuring under water currents to 1000 meters.  This instrument takes advantage of all the research acquired from the Phased Array Doppler Sodar development.
