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.
