3.1. Typical Radar Siting on Entrance or Exit Gate Masts
Each SmartSensor-Rail radar is a corner radar comprised of 16 individual radar elements with a
panoramic 90° by 140-ft. view. The ideal radar sensor mounting location is on each exit gate
mast or on each entrance gate mast. In this way, one side of the quarter-circle shaped detection
footprint is aligned with the crossing gates and the other side is positioned along the roadway.

If the crossing island is trapezoidal, choose the masts that provide an entire view for the 90°
footprint – from gates to a point beyond the side of the roadway view. Keep in mind that each
radar sensor’s 90
o
field of view (overall detection footprint) must cover the entire crossing island.
