Occlusion And Multipathing - Wavetronix SmartSensor V User Manual

Additional information
If the roadway is frequently used by tall vehicles, consider
˿
choosing a higher mounting height to help avoid occlusion.
Don't use an offset of less than 9 ft. (2.7 m). Also, the sensor can
˿
be up to 180 ft. (54.9 m) from the road, but don't go out that far if
you can avoid it; it could lead to decreased accuracy.
For best results, choose the mounting height in the Height
˿
column in the table. If you can't, just keep it somewhere in the
acceptable range.
