James bond anyone?
I truly hope these do not become common in the larger cities. :(
How would the military utilize one of these, they would be very obvious to anyone, even
radar, the only group of persons it could effectively be used on, would be the unprepared, without weapons to destroy the things.
Anyways,
"WHY jump in a cab to "follow that car" when an airborne drone could do the job for you? The US Pentagon's Defense Advanced Research Projects Agency is developing a radar system which sees around corners and down into "urban canyons". DARPA hopes to be able to track vehicles across an entire city using just a few uncrewed aircraft."
"Traditional radar relies on direct line of sight, so it's tricky to track a vehicle that keeps nipping behind buildings. But DARPA believes that by using buildings as mirrors, it will be possible to identify a target vehicle from radar reflections. The experimental system is called Multipath Exploitation Radar."
"By using buildings as mirrors, it will be possible to identify a target vehicle from radar reflections."
"Ain Sume of the Swedish Defence Research Agency says the "sound, well-known physical principles" behind MER make it feasible. His team built a radar system that detects people around a corner by using reflections from the opposite wall." :confused:
