3.1.3 Acquire and Measure Data
For details on data acquisition and measurement, refer to Section 3.4 “BASIC OPERATIONS” and Section 4
“MEASUREMENT OF RANGE AND BEARING.”
3.1.4 Display and Measure with Reference to CCRP
The radar video, range, bearing, Target Tracking and AIS data display etc... are displayed with reference to
CCRP (Consistent Common Reference Point).
If scanner is switched, these data are measured from CCRP.
If some kind of functions (for example off center, true motion, bearing scale, etc.) set scanner position to 75%
outside of the PPI range, these data except Target Tracking and AIS data are displayed with reference to scanner
position.
For how to setting CCRP, refer to Section 7.1.6 “Setting of CCRP/Antenna/GPS Antenna Position (CCRP
Setting).”
