ANALYSIS OF ANTIJAM COMMUNICATION REQUIREMENTS IN FADING MEDIA.

The effects are discussed of jamming in a multipath propagation environment in which both the desired signal and the jamming signal are subject to Rice or Rayleigh fading. The distribution of the ratio of two independent Rician random variables is calculated, and this result is related to the evaluation of the required processing gain for the case of air-to-air or air-to-ground communication in a hostile electronic environment. An example of a specific jamming scenario is employed to illustrate how these results can be used to estimate the required processing gain of an airborne UHF AJ communication system.
