When you say "below about 50mph (outside bandwidth?)" are talking about Doppler Shift due to speed? Just curious.
Yes, grasping for a cause of the driving speed effect.

Pretty sure the look down mode for the radar on an F-16 runs on an RF much, much higher than 600Hz. APG-66 is a 10-15GHz RF agile, pulsed Doppler system. I think you had interference from something else.

This could happen because the APG-66 and the speed radar detectors are both pulsed Doppler.

Police radars used the shifted frequency (Doppler shift) of their transmitted frequency to determine speed. An aircraft using radar that can measure doppler shifts allows it to do things like track objects on the ground that are moving when there is a lot of ground clutter.

True story.
