An Incoherent Doppler lidar (laser radar) is being developed at National Atmospheric Research Laboratory,Gadanki(13.5ºN, 79.2ºE), India to measure winds in troposphere and stratosphere. The lidar has a stabilised laser source, a telescope and a receiver. In the receive chain, the system employs a servo stabilised Fabry-Pérot Interferometer as a narrow pasband filter for measuring wind velocities. Calibration of receive chain with Fabry-Perot Interferometer is crucial for deriving the wind velocities. The developed calibration scheme gives two informations, one, the exact operation point of the Fabry-Pérot Interferometer and the second to generate “Lookup table” which is useful in deducing the winds. A software is developed for the purpose which is tested independently
