Figure 10-3: Body mask of the medium-sized car with roof-tops (Azimuth -180° to +180°)
1 = Roof
2 = Roof window
3 = Back window
4 = Seat
5 = Side window
6 = Front window
7 = Pass region (dark blue color): the incident signal is not attenuated and the table elements are set to 0 dB
8 = Attenuated pass region (light blue color): the incident signal is attenuated but not fully blocked; the table
elements are set to 15 dB.
9 = Non-pass region (red color): the incident signal is heavily blocked and the table elements are set to 40
dB
Possible application fields
●
Automotive applications
Attitude parameters are automatically extracted from the user-defined motion vec-
tor.
●
Body mask applications
Three files describe an antenna: the antenna pattern
*.ant_pat
(or power
response) file, the phase response
*.phase
file and the body mask file
*.body_mask
.
Antenna pattern and phase response files must have the same filename and must
be stored in the same directory.
If the required
*.phase
file does not exist, the carrier phase matrix is assumed to
be zero.
●
Outdoor scenarios
Antenna pattern are applied on reflections from the defined environment model, e.g
multi-path.
●
Indoor absorption scenarios
