Analysis of the Polarization Dependence of the Interaction between Human Frame Targets and Radio Frequency Sensor Fields.
Abstract
An analytical model of a class of RF intrusion sensor systems was constructed. The constituents of the model are: a slotted coaxial cable laid circularly on the ground, an electromagnetic scatterer intended to simulate a human frame target in the vicinity of the cable and an antenna near the center of the circular configuration. Using the concept of a general electromagnetic field as a superposition of plane-wave fields ('plane-wave spectral representation of fields'), calculations were made of: (a) the fields from the cable slots as if the cable were in free space; (b) the effect of ground reflections on the fields were from the slots; (c) the fields of the waves scattered from the human frame target directly toward the antenna in response to the incident wave fields ((a) plus (b); and (d) the effect of ground reflections on the scattered wave fields. These calculations were programmed for the VAX computer and some numerical results are presented for various orientations and positions of the human frame target. (Author)
