The application of artificial neural networks to naval ESM radar function identification

Identification is the last stage in ESM (electronic surveillance measures) processing, which is currently the radar type classification of each track. A track is a parametric description of a radar signal thought to be in the environment that results from the preceding stages of pulse sorting/grouping and characterisation. Identification consists essentially of an ESM radar library and an identification algorithm. The library describes the characteristics of known radars to be used by the identification algorithm. The identification algorithm defines the method by which the parameters of the track are matched against the library information and the result is a radar type identity for the track.
