ISAR 6.2.10

15.2. Example 2

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:
