Presentation On SODAR APPLICATIONS
[attachment=25445]
Introduction
WHAT IS SODAR?
Sound Detection And Ranging
Use RADAR Principles
SODAR Principle
Monostatic Principle
Bistatic Principle
Boundary Layer Studies
Troposphere average heights 6,10,11,18km
the first 1 km of the tropospheric environment, adjacent to the earth’s surface, is known as the lower planetary boundary layer (LPBL) or planetary boundary layer (PBL).
Average height of the LPBL also varies with respect to time and speed
Over ocean-average height may be only a few 100mtrs
On the plain land covered with green paddy fields and vegetation-1km appx
On over desert region-2km
Remote Sensing
Airport
Fire engineering(fire combating)
Analyzing clouds
Temperature
Water content
Seeding
Line Of Sight(LOS)
When we transmit a signal maximum distance that the transmitted signal can travel without much loss
For example:tele communication
Space shuttle
Fuel lines monitoring in space shuttle
Aircraft signaling
Microburst winds
Conclusion
SODAR system is a cheapest among LIDAR and RADAR systems for their applications because of the following:
SODAR senstivity is less
Field repairs can be done
