Microwave absorbers are a kind of material that can effectively absorb incident microwave energy to make objects invisible to radar. Recently, as radar detection devices have improved, scientists are ...

Computational imaging and microwave radar systems represent a synergistic research domain where advanced signal processing, innovative hardware architectures, and algorithmic developments converge to ...

MIT has been working on a prototype for a time of flight (TOF) microwave camera that can image objects through walls in 3D. The concept is a cross between a visible light camera and a radar imaging ...

On March 9, Nature Communications published research by Academician GUO Guangcan's team from the University of Science and Technology of China (USTC), which made significant progress in practical ...

Radar, at its simplest, involves sending out pulses of radiation that reflect off an object. The reflected signal is detected, and the time of flight is measured. The time of flight is then translated ...
