Execute the CF_generate_high_resolution_range_profile.luaapplication macro in CADFEKO to set up a
model and generate the data for a high-resolution range profile.
Open the Cylinder_HRRP.cfx in CADFEKO.
Execute the CF_generate_high_resolution_range_profile.luaapplication macro in CADFEKO.
The HRRP generation
dialog is displayed.
Figure 1. The HRRP generation dialog.
Under Definition method, select one of the following to
set up a high-resolution range profile:
Specify frequency (center) and range (ambiguity,
resolution).
Specify frequency (center, bandwidth, number of
samples).
Specify frequency (start, end, number of
samples).
Enter the required parameters.
If Specify frequency (center) and range (ambiguity,
resolution) was selected, specify the following parameters
under Frequency and
Down-range:
Enter the Center frequency (Hz).
Enter the Resolution (m).
Enter the Ambiguity (m).
If Specify frequency (center, bandwidth, number of
samples) was selected, specify the following parameters
under Frequency:
Enter the Center frequency (Hz).
Enter the Bandwidth (Hz).
Enter the Number of frequency samples.
If Specify frequency (start, end, number of
samples) was selected, specify the following parameters
under Frequency:
Enter the Start frequency (Hz).
Enter the Start frequency (Hz).
Enter the Number of frequency samples.
[Optional] Click Calculate to view the other dependent
parameters.
Under Phi, specify the plane wave source information for
the phi component of the plane wave.
Enter the Start (deg) angle in degrees.
Enter the Increment to specify the values
between the start and end.
Enter the End (deg) angle in degrees.
Note: Multiple incident angles are required to generate a 2D profile.
Under Theta, specify the plane wave source information
for the theta component of the plane wave.
Enter the Start (deg) angle in degrees.
Enter the Increment to specify the values between
the start and end angle.
Enter the End (deg) angle in degrees.
Under Polarisation, enter a value for the
Polarisation angle (deg) in degrees to specify the
plane wave source information for the polarisation of the plane wave.
Under Polarisation, select Calculate
orthogonal polarisations to activate the calculation of both
polarisations for the plane wave.
Click Generate to set up the model for the specific
high-resolution range profile.
View the generated HRRP model.
Note:
A configuration is created for the HRRP,
and any previous configurations are excluded.
Variables are created for each parameter, for example,
f_center for center frequency.
A far field request is added to the HRRP configuration and is set to
Calculate fields in plane wave incident
direction.
Figure 2. Example of the generated HRRP
model.
Run the model.
Tip: Use the “Farm RCS sweep to a cluster”application macro to speed up the simulation by dividing
the HRRP model over the frequency and angles of
incidence.
