There was a talk at DEFCON about this in 2012 [1]. The main issue is a radar system gets its information from ground-based measurements, while a GPS system gets its information from air-based measurements that are later transmitted to the ground station. This means that those reports can be spoofed, or lied about, or absent entirely.

- supernova87a 7y agoWell, as in the beginning of wifi/cell networks and all such similar technologies, their priority was to make a first adequate and reliable system that reports position. And getting operators to adopt it. Defeating bad actors was not a major requirement. Maybe if it's shown to be a great practical problem, they'll address it. If not, then no they won't. I'm guessing they won't.

This can further be cross checking with space-based systems like Nav Canada's: * https://en.wikipedia.org/wiki/Aireon https://en.wikipedia.org/wiki/Aireon
