In this example, the Bistatic RCS of a flare is calculated using a frequency sweep from 0.4 GHz to 0.6 GHz (400 MHz to 600 MHz).
Create a new project usingSTEP 1 to 5 discussed in Example1 above.
Click on Geometry → Solid →Flare.
Create flare command
Enter the following parameters to define the flare in the command line as shown in the next Figure:
· First corner of base [x y z]: -0.5 -1 0
· Base size [width depth]: 1 2
· Height: 2
· First corner of top [x y]: -0.25 -0.25
· Top size [width depth]: 0.5 0.5
