As an example of this, consider the fluctuations of the amplitude of a received wave. The expected statistical distribution can be obtained either by a direct calculation . or from fig. 14.3.

Johannes Hoogeveen,Andre-Marie Taptuée often associated with changes of the amplitude of the signals i.e. with the signal strength. In analogy to this effect, the angular spreading of waves as they propagate round the earth leads to effects of the strength of the received waves. For example, in the study of day-to-day bearing deviation

This remaining energy has not been scattered and thus it will always travel on a great circle path and will all pass through the point antipodal to the transmitter; the idealized type of antipodal focussing which was discussed in the first part of chapter 17 will occur there. In any practic
