    I rather doubt pulse width can be determined by the AL-P, PRR is a normal function.

    That's the unit Google uses.
    http://radarandlaserforum.com/showth...-(2-Available)

    And their website (datasheet) says: 300 RPM - 1200 RPM spin rate (user selectable)
    But it also says there are 4 groups of 16 emitters. Not sure if more than one beam per revolution could sweep past the ALP sensors and would be detected, but the ALP sensors are so sensitive, it seems possible.

    Maybe AL needs to acquire one of these units for analysis so they can filter out the falses? I heard that Google introduced some cars in Dallas, so they're spreading. Now they're putting them in Washington state too: http://dfw.cbslocal.com/2016/02/03/g...hington-state/
