CST2013: Farfield Plot – View

Farfield Plot: Plot Properties Properties View

Farfield and Structure view frame

These settings are only active if the 3D-plot type has been chosen. With these settings it is possible to plot the farfield and the structure at the same time. It is very helpful to realize the spatial relation between the main or side lopes and the modelled antenna.

Show structure: Enables to plot the structure into the 3D-farfield plot:.

Structure transparent: Only active if "Show structure" is selected. Plots the structure transparent. Use this option in cases the antenna obscures most of the farfield plot.

Farfield transparent: Plots the farfield transparent.

Farfield size slider: Only active if "Show structure" is selected. Moving this slider zooms the farfield plot without zooming the structure.

Color by value

In case of plot type 3D, use color ramp to map plot values to colors. Use the Color Ramp dialog to modify the mapping.

Draw step lines

In case of plot type 3D, draw black lines at each angular step. The step size can be set in the farfield plot dialog box. Step lines are not very useful in unzoomed plots with step sizes of 1 degree or below.

Draw iso longitude / latitude lines

Activates isolines for the longitude and latitude of the currently active coordinate system. These lines will be displayed together with farfield 3D plots.

Axes

Shows/hides the coordinate system visualization in the 3D farfield plot.

Pattern measurement lines

Visualizes the main lobe direction, the main lobe width and the side lobe level with auxiliary lines.

Color Ramp ...

Opens the Color Ramp dialog box allowing you to set your preferred color mapping for the 2D/3D farfield plots.

OK

Stores the current settings and closes the dialog box. Depending on the new settings a new plot of the farfields will be calculated. The calculation can be aborted by pressing the Abort button.

Apply

Stores the current settings leaving the Farfield Plot tab sheet opened. Depending on the new settings a new plot of the farfields will be calculated. The calculation can be aborted by pressing the Abort button.

FF View / Preview

Use this button to switch between farfield view and coordinate system preview. The latter hides the farfield and just shows the structure in respect to the defined coordinate system. In addition, Bistatic RCS results visualize the exciting plane wave. Leaving the preview mode with pressing Close restores axes, origin, and mirror plane settings.

Abort

Aborts the current calculation. Note that the last plot has been deleted. You will have to calculate a new plot by making the appropriate settings and pressing the OK or Apply button again.

Close

Closes this dialog box without performing any further action.

Help
