15.1. Example 1

In this example the Monostatic RCS of a plate is calculated.

Step 1

First, start newFASANT.

Starting window


Step 2

Create a new newFASANT project. To do this, select the File → New option (alternatively, the press Ctrl+N).

File menu 


Step 3

After selecting the New option, a list of the available modules is presented. The user needs to select a module from the available module list. Select MONCROS for this training example.

Module selection screen


Step 4

Select the Geometry → Surface → Plane option.

Geometry → Surface menu

Step 5

The command line panel requires some parameters at this point. Enter “-0.5 -0.5 0” as the first parameter and “1 1” as the second parameter so we create a 1x1 plane centered at the origin.

Step 6

Select the simulation parameters option.

 Simulation menu

Step 7

Select a frequency of 0.3 GHz (default options) and press Save.

Click on the “Advanced Options” button to set up other solver parameters:

Advanced parameters of solver, 'Main Properties' tab

Save the values for the advanced parameters of the solver.

Step 9

Select the RCS → Parameters option:

RCS menu

Step 10 

Select Monostatic RCS and leave the default parameters. Press the Save button.

Step 11 

Select Output → Observation directions.

Output menu

Step 12 

Leave the default observation directions (0.0 phi cut with theta angle varying between 0.0 and 180.0 using 181 samples).

Step 13 

Before running the simulation, select the Meshing → Create Mesh option.


Meshing menu

Step 14 

Set 10 divisions on planar and curved surfaces, set Processors to 1 and the default number of bands per octave. Press the Mesh button.
