Hello!

I studied the given tutorial related to radar cross section.

Unfortunately, these only provides how to plot monostatic RCS.

I tried to use parametric sweep, but it wasn't successful.

Can I get a clue in drawing bistatic RCS?

I desperately need your help.

Kim,

Bistatic RCS is much simpler than monostatic. To create bistatic RCS plot, do the following:

-Create 1D Plot Group or Polar Plot Group
-Create Line Graph and make line selection
-For ordinate axis, enter expression:

4*pi*(emw.normEfar/1[V/m])^2 for 3D model, or 2*pi*(emw.normEfar/1[V/m])^2 for 2D model

-For abscissa axis enter expression:

atan2(z,x), if your line is in the x-z plane

or
atan2(z,y), if your line is in the y-z plane

or
atan2(y,x), if your line is in the x-y plane

Regards,
Sergei

How to assign the x-axis expression was the most difficult topic to me!

Really, really, I appriciate your help. ^____________^
