3.5 Bandwidth Modes
The LPR
®
-1DHP-200 is able to operate in the 57 - 64 GHz band. Depending on your used
region and regulatory authority setting, a limited number of bandwidth modes are available
for selection in the WebUI.
The selected bandwidth modes have impact on the accuracy, resolution and range of the
radar. The dependency of performance and bandwidth mode with respect to regional
restrictions is depicted in chapter 10. It is recommended to use the 0.5 GHz or 2 GHz
bandwidth mode for standard applications.
Within a single bandwidth mode, multiple sync channels are available. For each channel
block, the effective bandwidth of a sync channel reduces with increasing sync channel
number.
3.6 Accuracy
To maximize the accuracy of a LPR
®
-1DHP-200 measurement setup, different error sources
which influence the accuracy need to be taken into account:
Mounting position
o
Adhere to the mounting instructions (see chapter 5) to minimize systematic errors
(e.g. horizontal or vertical offset and alignment).
Reflective surfaces and objects
o
Reflections of the radar signal, e.g. from walls, can cause distance errors in primary
and secondary radar mode which vary with the measured distance. Ensure the
recommended clearance to surfaces and objects described in chapter 5.1 or use
diversity radar mode to minimize errors caused by reflections.
Measurement noise
o
Measurement noise caused by the radar itself is the lower limit to the overall
accuracy. The noise will decrease with increasing bandwidth. For primary radar
mode, noise will increase with range and decrease with target radar cross section
