lovejeetA radio acoustic sounding system (RASS) is a system for measuring the atmospheric Lapse Rate using Backscatter of Radio waves from an Acoustics wave front to measure the Speed Of Sound at various heights above the ground. This is possible because the compression and rarefaction of air by an acoustic wave changes the Dielectric properties, producing partial reflection of the transmitted Radar signal.Radio Acoustic Sounding System Cite Note 0 From the speed of sound, the temperature of the air in the Planetary Boundary Layer can be computed. Radio Acoustic Sounding System Cite Note 1The maximum Altitude range of RASS systems is typically 750 meters, although observations have been reported up to 1.2 km in moist air.

p.s.- try googling the definition before posting the question, it will help you better........Radio Acoustic Sounding System Cite Note 2 -
vvishwaskumarthanx dear.. but there is some alteration in question.. actually i hv to ask " RASS characterstics of or in control system" so it is something related to control system..so help it out plz
