Development of ultra wideband antenna array for human detection under debris

Mega construction projects such as bridges and skyscapes are highly vulnerable to the natural disasters such as an earthquake, floods, and hurricanes. Any unfortunate accident may risk the life of residents living in such structures, the people might be trapped under the rubbles. Due to the reason,...
