Rich: I imagine that a good lawyer could argue that the radar is ISM, as it uses the emitted energy to profile the properties of a material, to wit, the Earth's atmosphere and those random discontinuities (like ships) that are distributed throughout the material. Although a valid point of view, I think I would still call a search radar RTTE rather than ISM. But now, imagine an atmosphere profiler. It's not looking for objects, it's looking at variations of the material. That's getting pretty close to ISM.
