Abstract
Some cases of super refraction observed with 3 cm. radars at different stations in India have been analysed. One of the significant features is the asymmetrical distribution of the duct with respect to the station; another is the fictitious display of some target heights. Ducts appear to be effectively present only in the small-scale anti-cyclonic regions near the station. The spurious height of the echoes is attributed to the presence of a sufficiently thick duct allowing different Gamow modes for different angles of aerial elevation.
