Applying the radiated emission to the specific emitter identification

During the last years we have observed fast development of the electronic devices and electronic warfare systems (EW). One of the most principal functions of the ESM/ELINT system is gathering basic information from the entire electromagnetic spectrum and its analysis. Simultaneously, utilization of some tools of artificial intelligence (AI) during the process of emitter identification is very important too. A significant role is played by Measurement and Signature Intelligence (MASINT) based on nonintentional emission (calls-radiated emission). This emission is a source of knowledge about an analysed emitter due to its incidental "chemical", "spectral" traces and noncommunication emitter's characteristics. The process of Specific emitter Identification (SEI) based on extraction of distinctive radiated emission features is presented by the authors. Specially important is utilization of a database (DB) in the process of identifying a detectable radar emission.
