Abstract
Specific Emitter Identification(SEI) methods are used in intercept systems for differentiating of same type of emitters in the environment. Most of the SEI implementations are designed for post processing (off line) by operators. This paper presents preliminary results on real time (on line)implementation of a SEI method on signals after the IF stage, i.e, video signals after the detector section. Initially, only the envelope of the pulses are considered in SEI processing. Pulse width and energy are two main parameters used in SEI algorithm developed. On the other hand, one of the main problems in operational environments is multipath distotion on received pulses. Most of the SEI algorithms require higher SNR figures for providing reliable results. Moreover, creating and running of a library is another issue. This paper presents various approaches in both processing of multipath distorted pulses and wavelet based library creating methods on real-time SEI implementation for an intercept receiver.
