Abstract: In this paper, the foundation of E-pulse (extinction pulse) method is considered as a possible way to design a target discrimination scheme using reflected responses for wideband electromagnetic incident pulse. The synthesis procedure of subsectional maximally smooth polynomial E-pulse appears to assume the equation taken for the number of sections, the number of natural resonances and the used polynomial order. In accordance with discrimination system structure, the E-pulse discrimination number dependency on section width and polynomial order is investigated. The results of statistical simulation for the two target problem show that E-pulse built for optimal parameters preserves enough discriminating potential for low signal-to-noise ratio.
