This is incorrect. Wifi systems that don't comply with DFS show up brightly on the radar display. Here's an example from a real-world system of what a misbehaving 5 GHz AP looks like:

The FCC has a list of WISP companies they've gone after for misconfiguring their wireless equipment:

Interesting, I'm genuinely surprised that's necessary. WiFi looks like white noise, and should be more or less trivial for a radar to reject.
If removing “noise” was trivial, we would all have perfect radios.
What makes you think that would be trivial?
Years of engineering experience in RF and DSP applications.

A radar that can be jammed by a WiFi access point amounts to an HR failure at the company that made it.

It's not jammed, it's dealing with a high noise floor and a weak signal.

You can only do so much to identify your own signal when it's smeared over a trillion water droplets.

I think you’ve misunderstood what we are talking about.

This isn’t jamming.

If it was trivial to identify signals from high noise situations all our radios would be perfect.
