Foliage Penetration Stripmap SAR Imaging Using UWB Random Noise Waveformprovides fine range resolution, while stripmap SAR image processing technique is used to obtain high cross-range resolution. In this paper, we present the random noise radar SAR imaging model, signal processing algorithms, and the 2-D imaging results obtained from field tests.

Object Impulse Response Evaluation for Ultrawideband Applicationis paper. Here, . is the output signal, . is the impulse response (IR) of the investigated object, . is the sounding pulse. The IR completely reflects the properties inherent to this object in the sounding pulse frequency band and can be used for its recognition.

Reversible and Irreversible Processes in Dispersive/Dissipative Optical Mediasically associated with incomplete energy accounting.. Specifically, we showed that for a dissipative dielectric, 1) there is an unambiguous notion of the total energy of the medium-field system, and 2) this total energy can in nowise demonstrate “fast” dynamics, neither locally nor globally.

Fast Time-Domain Integral Equation Approach for Wide-Band Pulse Propagation in Dispersive Mediaough there has been recently much interest in developing fast solution methods for time domain integral formulations of Helmholtz and Maxwell’s equations (Refs. .–.), relatively little attention has been given to the development of such tools for dispersive media, which pose a challenge from both analytic and numerical point of view.

Axial Scattering from Thin Conesbodies of revolution (BOR), including paraboloids and circular cones, seem to have good PO results as compared to exact and asymptotic results. However, the perfectly conducting angular sector is not approximated at all by PO (giving zero axial backscattering) for the case of the incident electric field parallel to the plane of the angular sector.
