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.
