Now, portable radar scanner to detect hidden weapons on people

London, Nov 15 : Scientists have developed prototype radar scanners that can detect weapons concealed on people in public spaces.

The device, which is designed to scan individuals in a crowd at a distance of up to 25m, could help security officials combat a wide range of threats, from hidden handguns and knives through to people wearing explosive vests, the BBC reported.

It is developed by a team at Manchester Metropolitan University and is set to undergo real-world testing next year.

The scanner uses low-power, millimetre-wave radar signals that reflect off a weapon and back to the scanner.

The device is fitted with an in-built computer that can determine the presence of dangerous objects and alerts the operator within seconds of detection.

The devices come in two forms. The first is as a mobile system that could be carried in a public space and has a range of 7-10m, while the second is a larger, static version that has an extended range of 20-25m and could be deployed at checkpoints or be mounted on vehicles.

According to the product makers, the scans will neither compromise people's privacy nor their health, as the devices do not produce an image of the subject but only analyse radar signals reflected from an individual.
