A gun that is hidden under a coat or shirt is nearly impossible to detect. A new gun-detecting radar could change all that and allows virtually anybody to detect hidden weapons.
Created by electrical engineering professor, Kamal Sarabandi of University of Michigan, this new technique use Doppler radar technology to detect guns using a system called “polarimetry.”
The device emits signals at a certain polarization and then analyzes the signals that bounce back. The type of signals that bounce off of skin and clothing are different from what would bounce off of an irregular metal object, which opens the window for gun-detecting hardware.
To be more precise, this new device would not necessarily be able to detect guns with perfect accuracy. Considering that it specifically detects metal objects, other items like smartphones could conceivably trick the device depending on how accurate the analysis software is.
A device like this could become a dream come true for security personnel and law enforcement officials. The device is handheld and could scan a person in under a second. In the not-so-distant future, police officers might be able to scan people to look for concealed weapons in much the same way that they scan highways with radar guns to see if any cars are breaking the speed limit.
However, researchers fear that 3D printed guns might be able to slip under the radar, so to speak, and fool this gun-detecting device.
Also, the device runs into complicated privacy issues. Using a radar gun to detect a car’s speed is one thing because it simply analyzes something that is plainly visible. Analyzing what a person keeps under his clothing without that person’s knowledge is a whole different story. What would be the point of carrying a concealed weapons if cameras could determine within seconds who is and is not carrying a weapon?
What is your take on this new technology? Are you excited to see it in action? Do you think that it will be the bane of gun owners everywhere? Are you more concerned with its potential impact on privacy rather than gun rights?
