Detect 'hot goods' thanks to mobile scanners

British scientists are developing a handheld scanner that uses microwaves, helping police identify individuals who carry guns or knives in secret.

The device is based on microwave radar technology and is designed to detect images of weapons under clothing. Some officials said that the technology could greatly support police forces in security checks.

The first prototype was used to identify guns, but researchers revealed that subsequent versions of the technology could also identify knives.

The handheld scanner uses low energy microwave waves, similar to the technology used for body scanners installed at airports. However, Professor Nick Bowring, Manchester Metropolitan University, head of the technology development team, said the device works on a different principle. Unlike airport scanners, this type of handset does not produce an image of an object, it only analyzes signals. 'It is designed to operate on the street and is not limited to a controlled environment , ' said Professor Bowring.

According to Professor Bowring, the handheld scanner works like a computer, thoroughly processing signals, connecting them and analyzing them in a short period of time and making decisions. It operates on the radar wave principle when illuminating people with guns and knives that look different from normal people.

Neurological analysis is also used to identify signals from weapons and differentiate them from other everyday objects. Similar technology has been used in automatic vehicle number recognition. Professor Bowring adds, his team is looking to reduce the number of false identifications to the lowest.

Tests are currently underway from the UK Central Police Technology Department. If successful, this device will be ready to operate in the police industry within two years.

Catherine Coates, head of the patent team of the Scientific and Technical Research Council (EPSRC), said: 'The device can save lives and save lives and save time for police police detection.'

According to Stuart Ibbotson, technical manager of the central police department: 'We are still in the early stages of evaluating the performance of the device, but I believe the results will be very positive in the future. This device is very useful for police officers, helping them to arrest criminals more easily without much danger. '

Professor Bowring revealed, handheld scanners have relatively cheap prices. The project involved researchers from Manchester University, Newcastle University and Queen Mary, financed by the EPSRC.
