Observations of Meteors using an over-the-horizon Radar
Publications Astronomical Society of Australia
AbstractWhen metre wavelength radars were first operated in the 1940s, echoes were obtained which could be attributed to backscatter from ionised trains produced by the ablation of meteroids in the upper atmosphere at altitudes near 100 km. Modern over-the-horizon skywave radars operating in the HF (High Frequency) band employ digital techniques for both radar control and signal processing and are aided by frequency management subsystems for the selection of appropriate frequencies for meteordoi:10.1017/s1323358000022992 fatcat:2mb22jtl6reephhrkphxymelgu
