2 Detection Performance Data
2.1 FMCW Narrowband Mode
Parameter Value
Basics:
Frequency Band 24.000 GHz to 24.250 GHz
Bandwidth < 100 MHz
Transmit Peak Power
(Individual Sensor)
<= 20dBm
Antenna:
Antenna Type Type 29
Angle Interval (field of View) Type 29: +-20 degree
Detection Performance:
Range Interval Minimum Range:
0.5m
Maximum Range:
Type 29: 180m/240m
(The figures are reflectivity and software limited, first
number is a typical value for a car as reflector,
second number max. output range)
Range Accuracy Typical: < 0.25m
General: 0.5m + 1%
Speed Interval Opening: -68.5m/s to –0.1m/s
Closing: +0.1m/s to +65.8m/s
Defined as absolute world co-ordinates, transformed
at run-time to relative speed intervals by using the
platform ego-speed.
Example: ego-speed = 0:
-70m/s (opening) m/s to +70 m/s (closing)
Example: ego-speed = 50m/s:
-20m/s (opening) m/s to +120 m/s (closing)
Speed Accuracy Typical: < 0.25 km/h
General: ±0.28 at –28m/s .. +28m/s
