1 Intended usage / application
The UMRR-09xx (UMRR) device is used as a field disturbance sensor. The user installs the
UMRR on a stationary or moving platform.
As soon as power is applied to the UMRR, transmit and receive start operating. The UMRR
sensor permanently monitors the volume within the vicinity of the antenna field pattern
(compare section 5).
The sensor itself is not rotated and has no moving parts.
The sensor acts in measurement cycles of 30 .. 150ms. Field disturbance is active throughout
every measurement cycle. Results are processed in parallel to watching the scene. Results
from the measurement cycles are transmitted on a CAN bus (optional RS485) every
measurement cycle.
The subject objects are typically road vehicles and pedestrians. Usually, subject
objects are expected within 200m .. 3m to the sensor.
A typical moved platform installation is behind the front bumper of a car.
Elevation orientation is almost parallel to the road surface.
A typical stationary application is mounted in above 2.5m height on a pole. Elevation
orientation is almost parallel to the road surface - elevation is less than 10
degrees.
All installations have in common that the user is free to select the azimuth orientation angle.
