Re: Not so certain- Detection?
I think this was alluded to with DPI...
Yup. Problem seems to be identifying drone + controller traffic amongst all the devices using the 2.4Ghz band, and there'd be a lot of those around an airport. So DPI might be able to profile the traffic as drone signals, and then it's how to locate those devices. So I guess radar might detect a drone, then try to isolate it's transmissions, then identify what it's transmitting to and find both endpoints.
But there's encryption to make that harder, and profiling based on SSID/MAC might not be reliable, especially if it's an open-source drone. And it still leaves the challenge of dealing with the drone, so don't know if it could be jammed/spoofed into thinking it's lost comms, then landing or returning to base.
