> ... can buy commercially now ...

The schedules, radar frequencies, etc. of those commercial satellites are all public knowledge.

(Based on timestamps) your reference is to user cutemonster's comment. Yep - "move immediately after the satellite passes" is a game that children can master. I would put a bit more weight on user walrus01's (later) sibling comment - on the problem of distinguishing small, pop-up air bases from routine civilian activities.

Also, I suspect that very few of those commercial satellite radars have much resilience in the face of jamming. That is expensive and security-sensitive tech on the satellite operator's end, of minimal use to most users of the satellites' services. Vs. in a war zone, the diplomatic consequences of using cheap (relative to getting hit) ECM against surveillance satellites will usually be the lesser evil.
