Paper Abstract

In this paper, we propose a novel chaos based ultra-wideband (UWB) sensor to enhance homeland security applications. The proposed chaos based modulation has a good resolution when used for wall penetrating applications. The receiver exploits the deterministic nature of chaos to cancel room reverberations avoiding complex synchronization procedure. Numerical electromagnetic (EM) simulations using finite difference time domain (FDTD) method are performed to illustrate the imaging performance of the proposed radar under real life surveillance situations with hidden and moving targets. The simulations are also employed to analyze the extent of penetrating ability of the proposed scheme for different structures. The effect of various structures and thickness on the detection performance are also commented upon.
