Abstract : High resolution, dual-frequency, VHF observations of meteors were conducted during 1964 and 1965 utilizing the DAZZLE radar at Central Bore, South Australia. An abridged description of the radar as it applies to these observations is given and full operational and data reduction procedures are discussed. Development of a fully automatic film reading program was undertaken and is also described. The data taken on three meteors at 55 MHz is discussed with emphasis given to trail echo characteristics as observed using short (0.5 microsec) pulses. An unexpected new phenomenon--long period (approximately 200 ms) cross-section variations--was discovered. Further work on the data including analysis of coherent phase returns is also discussed.
