Backscattering From Partially Convex Targets in Free Space With H-Beam Wave Incidence

Abstract

Abstract-In [9], scattering problems of plane and beam wave incidences were presented. In that study, it was found that the target configuration together with beam width have a major effect on the laser RCS (LRCS). This conclusion was proved for horizontal incident wave polarization (E-polarization) in free space. The polarization of incident waves is one of the key parameters in the scattering problems and in particular in the resonance region where the target has a comparable size with the wave length. In this work, we extend our study and investigate the impact of vertical incident wave polarization (H-polarization) on the LRCS of large size targets and compare it with RCS of targets with plane wave incidence.

“…The resonance poles in terms of ka are the same as those with H-wave incidence shown in [20,21]. Moreover, resonance occurs here with the same parameters of SCL where target aspects, as is the case with H-wave incidence, include complexity and illumination region.…”
