ABSTRACT
This chapter is devoted to the theory of backscattering of ultrawideband (UWB) pulse signal from perfect electrically conducting (PEC) large objects. The analysis considers targets located near the boundary of uniform half-space with both real and complex electrical parameters. The approach uses a high-frequency (physical optics approach) approximation of pulse (transient) wavefront characteristics to calculate the UWB response of the object by convolution transformation. The calculation method uses developed Želd integral representations and the high-frequency approximation of a (PEC) object pulse characteristic (PC) in a general bistatic case for oblique incidence. This also deals with the problem of UWB signal scattering from the half-space, representing a layered uniform medium with
