Abstract:

Recent developments in the area of digital ionosondes and computer technology have enabled systems to be developed in which virtual heights and echo amplitudes obtained may be translated directly into true height profiles, sky maps and frequency management charts. Real time ionogram evaluation will enable users to make highly accurate judgements as to the proper selection of frequencies for short and long range HF communications. Libraries of previous ionograms make ionospheric predictions considerably more accurate. The spectral analysis of data taken utilizing an array of receiving antennas allows the user to spatially locate traveling ionospheric disturbances. This system gives the specific location of the echos reflecting surface and its motion with respect to the users position. Author
