Configuration for Imaging Parameters of RadarImager#
taskImaging#
The imaging section provides all necessary parameters to select the relevant data from the recorded data to generate an image.
The transpose and flip nodes contains parameters that allow to manipulate the orientation of the image. This can be useful to align the image with the physical orientation of the object being measured. By combining all these nodes, it is possible to display any image orientation.
layerSelection.indexes#
This parameter allows you to select the layer of the recorded data that should be displayed in the image. The layer index corresponds to a specific distance from the RadarImager (z-axis).
The layer with index 0 corresponds to a distance of 100 mm to the RadarImager, as layers with a lower distance are not selectable. The distance between two selectable layers is 2.726 mm.
If layer index 1 is selected, the index corresponds to a distance of 100 + 1 * 2.726 mm to the RadarImager. Layer index 2 corresponds to a distance of 100 + 2 * 2.726 mm, and so on.
Restriction based on parameter dependency
The maximum selectable layer index is limited by the measurement configuration parameter distanceZToDeepestLayerOfInterest.
The distance to the RadarImager (z-axis) corresponding to the layer index cannot exceed this parameter configuration.

Slide through the layers with the layerSelection.indexes parameter to find the object of interest:
The globalScale parameter can be used to find the object more easily.
GenDC
- If the container mode is enabled and multiple layers are to be transferred simultaneously, the desired layers should be listed separated by commas.
- The first layer starts at 0.
- Be aware of the GenDC limitations
GenDC limtations
Example
- To receive layers 0, 1, and 2, use the list: 0,1,2
- For transmitting layers 2, 5, 10 and 11 use the list: 2,5,10,11
flip.dim_1#
This parameter allows to mirror the image along the moving direction (x-axis).
| Property | Value |
|---|---|
| type | Option |
| Default Flag | false |
flip.dim_2#
This parameter allows to mirror the image in the antenna direction (y-axis).
| Property | Value |
|---|---|
| type | Option |
| Default Flag | false |
channelSelection.conversion#
This parameter allows you to select the type of data that should be used to generate the image.
It is possible to choose between absolute values [ABS], phase information [PHASE], or a combination of both [ABS_PHASE].
Through the later coloring configuration it is possible to combine this information and generate a phase image whose brightness is weighted based on the absolute values.
| Property | Value |
|---|---|
| type | Enum |
| Default Value | ABS |
| elements | [ABS, PHASE, ABS_PHASE] |
channelSelection ABS (left), PHASE (middle) and ABS_PHASE (right):
Learn more about the phase information and how to use it for specific use cases in the Radar Imager Basics guide.
transpose#
This parameter allows you to swap the x and y dimensions of the image.
Default setting
By the default setting the movement direction (x-axis) is displayed horizontally and the antenna direction (y-axis) is displayed vertically.
| Property | Value |
|---|---|
| type | Option |
| Default Flag | false |
globalScale#
This parameter determines how the image data is scaled.
If disabled, each layer selected in layerSelection.indexes is scaled individually based on its own min and max values.
If enabled, all layers are scaled based on the min and max values of all selectable layers in layerSelection.indexes.
This can be useful when comparing layers to identify those with particularly high reflection factors.
This is very often close to the layer of interest.
This parameter is only relevant for images that contain abs information, as the phase information is always in the same range of 2π.
| Property | Value |

| type | Option |
| Default Flag | false |
