mode
Directivity: Norm the plot to the total radiated power.
See Farfield Overview for
more information.
Gain (IEEE): Norm the plot to
the total input power. See Farfield Overview
for more information.
Realized
Gain: gain * (1-Balance^2), includes the impedance
mismatch loss.
RCS
(m2): Show the radar cross section scaled in square meter. Project
length units squared are also available. See Farfield
Overview for more information.
RCS
(sw): Show the radar cross section scaled in square wavelengths.
See Farfield
Overview for more information.
E-Field: Show the e-field value in the farfield at the
reference distance.
E-pattern: Show the e-field radiation pattern.
H-Field: Show the h-field value
in the farfield at the reference distance.
Power pattern: Show the power value in the farfield at
the reference distance.
Linear scaling: Check here to get a linear plot.
Inverted IEEE axial ratio: Plot the inverse of the IEEE axial
ratio.
Reference
distance: Set the radius of the virtual sphere for which the farfield
is calculated. Available for plot modes e-field / h-field and power pattern.
Use
farfield approximation: If turned off the fields will be calculated
without approximation and contain radial components. Please note that
switching off the approximation will increase the calculation time. The
farfield approximation can only be turned off for the E-Field plot mode
and H-Field plot mode without lossy mirror plane.
dBV/m, dBA/m, dBW/m2 / 鈥? Set
here the desired physical unit for both linearly and logarithmically scaled
farfields. Maximum = 0 dB / Maximum = 1 normalizes the farfield to the
plot maximum.
1D Plot Options: Opens the plot options dialog
for polar and cartesian farfields.
Log.
range [dB]: Set here the range in dB you want to be plotted. For plot
types Cartesian, 2D and 3D, the plotted minimum value will be max-range.
For plot type Polar, the plot will be scaled to the next 10 dB step above
the maximum (i.e., 20 dB if the maximum is 14 dB). The plot range is automatically
extended if the specified range contains only a single data point.
Normalization
[dB]: Sets the reference value (in dB) which is
scaled to 0 dB.
Use current max.: Sets the current plot maximum as dB scaling
reference.
Maximum plot value frame
Select here the
type of plot maximum for the farfield plots.
Use automatically determined variable plot
maximum: Check
here to use an automatically determined plot maximum. The plot maximum
is recalculated for each farfield plot type and mode.
Set user defined maximum plot value: Check
here to use a fixed plot maximum for all 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 shows only 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.
