Basic Sodar System operating Monostatic / Doppler mode" has been designed and developed which measures thermal picture/ wind profiles of the lowest 1 km region of the atmosphere, through remote sensing. In this equipment, powerful pulse of sound is transmitted vertically up into the atmosphere and echo returns from thermal inhomogeneities are received back. The backscattered component is plotted as a facsimile picture of the atmosphere, revealing three dimensional plotted to yield wind profile. The entire operation and data capturing is handled automatically by an IBM compatible PC.
