This section explains how to obtain the ISAR image of a rectangle-shaped geometry.
Step 1. The first step consists of creating a new data file where all the parameters of the simulation will be saved. Use the command ‘New’ from the File menu. Select ISAR type.
Selection Method dialog box
Step 2. Generate the geometry by selecting Geometry->Surface->Plane. The dimensions of the rectangle are 1 x 1 m.
Create a plane
Step 3. The next step is to configure the parameters of the simulation, which are located in the Parameters menu. In the ISAR menu introduce the following parameters:

Step 4. Select Monostatic RCS for this example. The wave is theta polarized: Etheta = (1.0,0.0).
Step 5. In the Solver Menu select the Method of Moments option.
Step 6. Set the observation direction. Use the Observation Directions option from the Output menu.
Step 7. Mesh the geometry by selecting Meshing->Create Mesh.
Step 8. Click on Calculate->Execute.
Step 9. Select Show Results->ISAR image.
Step 10. Select Show Results->View Currents.
Step 11. Select Show Results->View Charge.
