Applying the distance and similarity functions to radar signals identification

One of the principal functions of the ESM/ELINT system is gathering basic information from entire electromagnetic spectrum and its analysis. In most cases, based only on primary features of incoming radar signals, the modern electronic intelligence system cannot recognize the different devices of the same type or class. A very important role is played by Measurement and Signature Intelligence (MASINT). The process of Specific Emitter Identification (SEI) based on extraction of distinctive radiated emission features and final emitter identification based on ldquothe knowledge-based approachrdquo [1, 2], generally is not enough to identify detectable radar emission.
