Abstract

A novel chaotic modulated ultra wideband (UWB) synthetic aperture radar (SAR) imaging scheme and its post data processing technique are presented for through the wall surveillance applications. It is illustrated that the proposed radar has an excellent resolution performance due to the autocorrelation properties of chaotic signals. Through modeling room reverberation and target reflection, and deriving energy distribution at the receiver, detection performance is carried out to show the advantages of proposed radar. Electromagnetic (EM) simulations are performed in a through the wall scenario. Compared with the conventional UWB radar, the result verifies the effectiveness and superiority of the proposed technique.
