Preliminary observations using ST mode of Indian MST Radar: detection of the signature of the tropopause

An MST (mesosphere/stratosphere/troposphere) radar is currently under installation at Gadanki, a low latitude station in India. As an intermediate step, a low power-aperture version of the system was operated in the ST mode. The paper gives an account on the salient features of the system and presents preliminary observations conducted on the detection of the tropopause. The observations clearly demonstrate the potential of the radar to carry out high resolution studies on the tropopause above this tropical station.
