Ku and mid ka, high ka band spectrum analyzers are no longer a $40,000 item anymore. I'm pretty confident I could put together a (starlink, kuiper, oneweb) locating kit for under $10k USD. The knowledge to run a spectrum analyzer just to locate on class of equipment could be taught to any moderately educated local police in one day.

Not much is using these bands anyway, especially in places like Iraq. Wouldn't it be even simpler to skip the spectrum analyzer and sweep the area with high-gain antennas tuned for these bands, the fox-hunting way?

Ku and ka aimed at the sky doesn't propagate like vhf, uhf. You'd need fairly high gain horn antennas to detect off-axial-aim emissions.
