Re: Evolution
That's why police switched to Ka-band radars which use a different frequency (34 GHz) that required different hardware to jam. Then along came LiDAR which can be used in quick pulses that were difficult to detect before you were already measured. Because of the ways they were used (most use encoding so can beat passive jammers), active jammers for them could be detected as well and flagged as worthy of stopping in themselves (because radio jammers are against the FCC regulations and LiDAR jammers fall afoul of varying state laws).
