Interferometric radar observations of meteors at widely separated locations
Abstract
Back-scatter radars have been operated simultaneously and on a continuous basis at Tavistock, near London, Canada and near Sao Paulo, Brazil. Each system consists of five separate receiving antennas arranged as two orthogonal 3-element arrays that allows the unambiguous determination of the direction in space of the meteor echo relative to the station location. The antennas used are two-element Yagi type with horizontal elements and pointed vertically upwards to give all round coverage. Aside from the operating frequency, 29.3 MHz in Canada and 34.2 MHz in Brazil, the systems are identical. Results from these operations during the time of the 1999 Geminids are presented illustrating the similarities and differences arising from the significantly different site coordinates.
