How about RTL-SDR detecting SAR signal?

I just wonder how many SAR sats we don't know about.

Won't work with a regular RTL-SDR.

Most SAR systems operate in X-Band (~10 Ghz). I guess it's fair to assume that every organization who has ever sent anything to space has also launched SAR satellites. The radar part is comparatively easy to getting things into orbit.
