The article does a lot of talking without actually saying anything. I suppose that vagueness is intentional, rather than just the hallmark of a poor writer.
We are led to guess just how an airborne radar can provide intelligence on land-based operations. Can it distinguish presence of or movement of metallic vehicles from other ground features? Does the system have the capability of detecting radio transmission signatures or engine heat signatures, or even body heat signatures? Is it even radar that we are talking about, or is it some kind of multi-sensor package that is being employed? Does the system capture data that can then be reviewd in a sensor-fused, time-lapse fashion to deduce troop and/or munitions movements?
The enemy is not known to be using aircraft, and so the discussion of the Falklands experience would seem to be missing some context.
So, can anybody translate for me what’s going on, or do I lack the requisite level of clearance for that info?
Here is Thales' description of the Searchwater 2000 radar:

In addition to the usual air-to-air search mode that you'd expect from an airborne early warning radar, the Searchwater radar also has a surface mode to detect moving targets, and the ability to operate over land.
This would help to identify tanks and convoys, as well as other surface traffic both on land and close to shore.
Beyond that, I suppose your imagination will have to do.
