Presently, modeling techniques have been established for radio frequency interference prediction in search radars. Modeling techniques for the special group of radars, classified as tracking radars, are relatively new and require further development before an adequate prediction model can be realized. The nature and aspect of a tracking radar prediction model depends upon the various forms of degradation that the system experiences in the presence of an interference environment. This degradation is dependent upon the functional mode of operation, search, acquisition, and track. The corresponding prediction techniques are also dependent upon these functional modes. This paper presents the results of an analysis to determine the effects of interference on tracking radars and to derive methods for designing mathematical models that can be used for predicting the effects.
