Abstract : Techniques for the recording and analysis of phase variations of pulse modulated ground backscatter data are discussed. It is shown that these techniques are capable of yielding additional information about the characteristics of layers of the ionosphere capable of supporting ground backscatter. The formation and motion of ionospheric irregularities of electron density are easily determined by these techniques. An effort was made to determine whether or not it is possible to detect any difference between land and sea slant backscatter. It was found that at the high frequencies (8 to 64 mHz) used in the experiment the solar control effect on the F-2 layer in the directions from 90 degrees to 180 degrees to 270 degrees was very much larger than the possible difference between land and sea backscatter that it rendered impractical the detection of this difference.
