Abstract : There is a increasing interest in the effects of meteors on the upper atmosphere and ionosphere. The use of narrow beam MST radar for detection of meteoric phenomena is a proven technique that has number of avenues to be explored. The use of MST radars allows us to study the meteor population which probably contributes the most extraterrestrial material to the Earth’s upper atmosphere. In spite of its installation about two decades ago, only few meteor observations have been made at the Gadanki MST radar. The purpose of this paper is to highlight the strengths of the Gadanki radar for meteor observations. Since the transmitter output power of this radar is approximately 40 times higher compared to the output power of classical meteor radars, hence a direct probing with improved sampling resolution is possible. A better understanding of the limitations associated with narrow beam MST radar system is important for comparison studies of meteor activity with other observational instruments. In addition we present here characterisation of the meteor reflections process and the corresponding signal analysis for some of the echoes.
