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.

Multisensor Data Fusion for Life Detection in Cluttered Environments

IEEE Sensors Journal, 2022
A multisensor data fusion algorithm is proposed in this study for life detection in cluttered environments. The method consists of four steps: data acquisition, data preprocessing, data fusion, and result sort.

Understanding planetary context to enable life detection on exoplanets and test the Copernican principle

Nature Astronomy, 2022
The search for life on exoplanets is motivated by the universal ways in which life could modify its planetary environment. Atmospheric gases such as oxygen and methane are promising candidates for such environmental modification due to the evolutionary ...

UAV Life Detection and Rescue Using Group Role Assignment

IEEE International Conference on Systems, Man and Cybernetics, 2022
With the frequent occurrence of disasters, such as war, storms, hurricanes, and earthquakes, post-disaster rescue is particularly important. Based on the principle of life first life detection and rescue have become the primary task of post-disaster ...
