horizontal pivoting angle, in normal condition, the radar beam should cover the monitoring lanes evenly.
Figure 4.2: radar horizontal pivoting angle modify reference sketch map
In a word
，
the ultimate purpose of installation modify, is assure the radar beam
radiate the region
nearby the radar trigger area(neither higher nor lower), the radar beam cover the monitoring lanes
evenly(neither too left nor too right), as far as possible .
On upper computer, two kinds of target vehicle display mode can be used
（
1
）
continuous mode: it
means radar send data to upper computer continuously and upper computer display target vehicle
continuously, just like forming a movement locus
（
2
）
contact mode: it means radar send data to upper
computer only if target pass through the trigger line, just like number counting of vehicle.
In detail performance standard, for 3 lanes monitoring, if no display omission after 60 vehicles pass
by continuously ,debugging and calibration can be considered to be finished .for 4 lanes monitoring, if
no display omission after 80 vehicles pass by continuously ,debugging and calibration can be considered
to be finished.
After the debugging and calibration, connect the radar to camera, refer to table 3.3
