Test site was a two-lane country road free of traffic. Each laser was tripod-mounted and placed on the opposite shoulder of the vehicle's path, purposely inducing a 3-degree cosine error to test the jammers' ability to defeat an off-axis laser beam. The front license plate was targeted and each laser's sighting reticule remained on that target for the duration of the run. Test vehicle made three runs from 1000 feet and the distances were recorded at which continuous target speeds could be obtained. This number is expressed as JT (Jammed-To) followed by the target distance (in feet) where the laser gun could begin tracking the vehicle.
The average of the three runs against each model laser is listed.
Effectiveness rating determined by the jammer's ability to prevent target speeds from being obtained until target vehicle was within 450 feet of laser gun. Effectiveness rating determined by a) dividing 450 by the jam-to range in each column (100% maximum score), b) adding the effectiveness percentage in each column and dividing by 5 to determine the overall effectiveness rating.
