This is something they will love over at “24” and its fictitious and nearly omnipotent Counter Terrorist Unit. The Pentagon’s Defense Advanced Research Projects Agency is developing a radar system that can track suspects or vehicles around corners and “down into urban canyons”— essentially anywhere in a city.
Using a few unmanned air drones, DARPA will use the new Multipath Exploitation Radar to create 3-D urban maps and something called a Ku-band radar, which will run at high enough frequencies to get detailed images of vehicles. The drones bounce radars off the ground and buildings and match the patterns to 3-D maps, creating a full, vivid picture of a city in motion.
