Abstract:

This report describes an estimation procedure for determining the critical frequency of the ionospheric F2 layer. The estimate is obtained from measurements of radio noise obtained by a satellite orbiting above the F2 layer. A spectrum analyzer obtains noise power as a function of frequency in a band wide enough to include all possible values of the critical frequency. Author
