This cat-and-mouse game has been going on for a long time, even outside of spycraft.
E.g. radar detectors are illegal in several states, so of course there have been devices sold to law enforcement to allow them to detect these illegal radar detectors. https://en.wikipedia.org/wiki/Radar_detector_detector https://en.wikipedia.org/wiki/Radar_detector_detector
That's all probably moot now. I think law enforcement has moved mostly to using lasers, which are much more difficult to detect.
- sandworm101 10y agoThe handheld units are now universally laser, but there are a couple places where radar is still the norm. Some cops have car-mounted radar units so they don't need to get out of, or open the window of the car. These are great if you want to watch a highway that doesn't get much traffic or to catch speeders while your own car is moving. Both scenarios are very common in rural areas. Also, automated speed detection systems (aka "photo radar") use radar because you don't have to aim it like you do a laser.
- codethief 10y ago> This form of "electronic warfare" cuts both ways and since detector-detectors use a similar superheterodyne receiver, many early "stealth" radar detectors were equipped with a radar-detector-detector-detector circuit, which shuts down the main radar receiver when the detector-detector's signal is detected, thus preventing detection by such equipment. TIL there exist radar detector detector detectors.
