A report on the English.cri.cn website claims that China has completed research and development of a new radar system, which can penetrate walls and provide scanning imagery of objects inside houses.
According to the report, China Electronic Technology Corporation (CETC) has completed the prototype R&D of China’s first all-solid-state Terahertz imaging radar system. The R&D of this new radar system took over two years to achieve major research progress.
Terahertz technology has been a research hotspot in recent years. Terahertz signals carry high frequencies; have short wavelengths (1 millimeter down to 30 micrometers), high temporal-frequency spectrum signal to noise ratio and low transmission loss in dense smoke-filled or dusty environments. It can go through walls and scan objects inside of houses, which is an ideal technology for the environment of battlefields.
In urban combat and anti-terrorist combat in the future, the Terahertz imaging radar system can provide 3D stereoscopic imaging of objects behind walls; detect concealed weapons and militants under disguise and show tanks, artillery and other equipment even hidden by smoke.
