A novel chaos-based high-resolution imaging technique and its application to through-the-wall imaging

In this letter, we present a novel chaos-based imaging technique. The proposed technique has good range-Doppler resolution and excellent side lobe suppression characteristics that promise immense potential for high-resolution imaging applications. We derive the range and Doppler resolution functions of the proposed technique and compare it with that of conventional time modulation-based imaging. Additionally, the noise performance of the proposed scheme is derived to show the improvement compared to the conventional amplitude and time modulation schemes. The proposed imaging technique is applied to through the-wall radar imaging. Numerical electromagnetic simulations are performed to illustrate the effectiveness of the proposed technique.
