Radar observations of meteor trails
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract A Fresnel Transform technique has been developed at Adelaide to analyse radar meteor echoes detected in the transverse mode. The genesis for this technique was the study of the structure of the scattering ionization immediately behind the head of the trai...

متن کاملInterpretation of non-specular radar meteor trails
[1] Radar data of non-specular meteor trails shows two clear and consistent features: (1) non–specular meteor trails are observed from a narrower altitude range than are head echoes and (2) an approximately 20 ms delay between meteor head echoes and trail radar scatter. This paper shows that both features can result from meteor trail plasma instability. Simulations have demonstrated that trails...
متن کاملMeteor Observations with an MF Radar 1
We conducted meteor echo observations using the Buckland Park MF radar (35 S, 138 E) at 00:40{05:45LT on October 22, 1997. In addition to the usual full correlation analysis (FCA) technique to measure horizontal wind velocities from 60 to 100 km MF radars have a potential to detect meteor echoes and infer winds through their Doppler frequency shifts. Because of the relatively low radio frequenc...
متن کاملAnalysis of ALTAIR 1998 meteor radar data
[1] We describe a new analysis of a set of 32 UHF meteor radar traces recorded with the 422 MHz Advanced Research Project Agency Long‐Range Tracking and Identification Radar facility in November 1998. Emphasis is on the absolute velocity measurements and inferences that can be drawn from them regarding the meteoroid masses and mass densities. We find that the 3‐D velocity versus altitude data c...
