Radar sweeps, it takes time to get back, it takes time to relay information and it takes time to respond. When you have aircraft moving at hundreds of miles an hour crossing in close proximity the trajectory can change and result in impact before radar can gather data, assess it, make a prediction and relay that information.

The radar can make a prediction, and automatically send the warning to the airplanes on a collision course.

All well within what we can do with radar and computers and radio today.
