Signal sorting in ESM systems

The paper discusses the problem of developing automatic sorting of radar environments, in order to assist, and eventually replace, the ESM (electronic support measures) equipment operator. The paper separates the signal sorting problem into two subproblems of describing the radar environment in a pulse-train sorter and monitoring changes in the perceived environment in a new-signal detector. Emphasis is placed on the need to use all available pulse parameter measurement data in order to achieve the highest possible confidence in the descriptions of the emitters which the signal sorter provides.
