What happens when advances in modern electronics mean that sensors like imaging-class radars, advanced day/night cameras, and even more exotic items like hyperspectral sensors, laser radars, etc. are no longer very expensive items that are mounted on dedicated platforms? When a wide array of video cameras, surveillance turrets, ubiquitous radar capabilities, and other systems built into vehicles, aircraft, ships, and unmanned vehicles provide an explosion of sensor data – just as a range of databases related to human patterns or physical infrastructure are also appearing on the scene, in numbers.
In part, it is similar to what happened when the Internet went from an academic platform to a global phenomenon. The good news was, so much more information became available. The bad news was, finding the things we were looking for started to involve a lot more work.
The military has this same problem with sensors, only worse. Most of the time, they’re not necessarily looking for discrete answers, but for an overall picture of what’s going on. That becomes hard as sensors move from a small number deployed on dedicated platforms, to hundreds or thousands of them employed in platforms of every shape and size. For some applications, like domestic security or protecting certain key areas, it gets even harder. The need to include physical surveillance, communications surveillance, information about human activities, and improved geo-awareness all combine to produce a maddeningly complex task.
Moore’s Law of doubling computing power, and Metcalfe’s Law of exponential network power, created this data explosion. Several cycles later, the military is hoping it can begin to offer assistance, by turning massive arrays of data into coherent systems that help humans respond at the speed of events. The first step was data fusion. The next step was sensor fusion. The third step is information fusion… and the US Navy has just set up a center to work on it.
