So instead of jamming of "constant, varying" signal, why not jam with a
signal that would make the radar gun thinks you're going 20mph (or of your
liking) below your actual speed? The jammer would be wired to the
speedometer or something. The primary jamming should be strong, with a
weaker random signal to mask the original radar wave from the radar gun?
Would that trigger the jammer detection?
