Figure 1.3: Definitions for WaveGuide Direction-OnBoard 2 systems.
The proper installation of a WaveGuide Direction-OnBoard 2 array of radar sensors requires
understanding the following naming conventions and standards:
• Each of the three radars, defined by its serial number, is given a functional name (A,
B or C). If necessary it is possible to adjust these relations through the user interface.
• By definition, radar B will always be positioned on the right side of the line A-C, or
in the case of a line array on the line A-C.
• The positions of radars A and C define the array orientation with respect to the
reference North.
• When specifying a tilt angle for radar B and C, the tilting direction will be aligned
with the position of radar A and the tilt angle will be positive when tilting away from
A. (Right hand rule in Fig. 1.3.)
• It is very important to correctly position and orient Radar A:
–
Radar A must be a WaveGuide Onboard 2 sensor.
–
The symmetry axis of radar A must align with the center of the angle formed
by the AB & AC lines.
– When specifying a tilt angle for radar A the tilting direction must align with the
center of the angle formed by the lines AB & AC. The rotation axis follows the
right hand rule as shown in Fig 1.3.
• On the "Configuration -> Sensor" page of the web-interface the following parame-
ters can be found (more information about accessing and using the web-interface is
available in Chapter 3):
–
Distances between radars A, B and C.
–
The angle from the reference North to A to C.
– Relation between the radar A, B and C (functional) and the physical radars
defined by their serial number.
–
The configuration parameters and reflection diagrams of the selected radar.
