Key points of CSR-IM multi-target Radar Debug
Operator first time implement multi-target radar installation should pay attention
to the following key points and thoughts:
1.
make sure the radar installation up-down pitching angle (declination angle) and left-right pivoting
angle(deflection angle) are within proper range, so that radar beam cover the monitoring lanes evenly
；
Cover the region where nearby the radar trigger area to assure radar can detect and monitor vehicles in
lanes efficiently, realizing vehicle recognition correctly, speed-measurement positioning precisely and
triggering camera to snapshot.
Modifying the pitching angle and pivoting angle of radar will affect the region the radar can cover.
As shown in figure 4.1, the radar radiate position will be changed as changing radar up-down pitching
angle, in normal condition, the region that the radar beam cover is where nearby the triggering distance.
