Chaos-Based Through-Wall Life-Detection Radar

International Journal of Bifurcation and Chaos, 2019
We propose a chaos-based through-wall life-detection radar utilizing a wideband Boolean-chaos signal as the radar probe signal. The range between the radar and the human target can be obtained by correlating the chaotic signal reflected from the human target with its delayed duplicate. Actually, this range is modulated periodically by human chest wall

Deep Mutual GAN for Life-Detection Radar Super Resolution

IEEE Geoscience and Remote Sensing Letters, 2022
To improve the life-detection radar resolution under certain hardware conditions, in this letter, a deep mutual learning generative adversarial network model (Deep Mutual GAN) is proposed.
