Abstract :
In this paper, we present a novel chaos based ultra-wideband (UWB) imaging radar for surveillance applications in a closed environment. The proposed chaos based UWB imaging radar has good range resolution and excellent range-sidelobe suppression characteristics that enhance its imaging performance. The imaging performance of the proposed radar is better than that of the conventional time modulated UWB (TM-UWB) radars in reducing false alarms and in imaging targets closely lying behind the wall. Numerical electromagnetic (EM) simulations using finite difference time domain (FDTD) method illustrate the definite advantages of the proposed radar under different scenarios.
