Analysis of a Backscatter Signature Obtained with a High-Resolution HF Radar System


  • Robert D. Hunsucker


One particular backscatter signature obtained with an HF narrow-beam scan backscatter sounder system is analyzed by considering its behavior statistics and applying a three-dimensional computer ray-tracing technique. Other simultaneous radio data are used to modify the theoretical model. Results of this investigation indicate that this particular signature probably is the result of medium-scale traveling ionospheric disturbances which are the ionospheric manifestations of internal atmospheric gravity waves.
