XENSIV™ BGT60LTR11AIP shield
60 GHz radar system platform
Measurement results
6.2.2
SPI mode and MMIC internal detector
•
Hardware
DEMO BGT60LTR11AIP, consisting of the Radar Baseboard MCU7 + BGT60LTR11AIP shield (which is
configured by default in SPI pulsed mode)
•
Firmware
Is only used to set the shield configuration by writing to the MMIC SPI registers, as shown in Figure 23 (a).
The “Radar Integrated Motion Sensing” application available from the Radar Fusion GUI is used.
•
Height
Board is placed at 1.2 m
•
Scenario
Measure the max. detection range of a human target along the H-plane and E-plane of the sensor, for
different threshold values, which can be selected from the GUI, and different angles.
•
Detection status
Is driven from the internal detector output (TDet). Figure 25 and Figure 26 show respectively the
measurement results in H-plane and E-plane, and the right shield orientation.
