Hi everybody,
I have to simulate the scattering of a bistatic radar with a metal ball target.
I am using the FEBI option so both the antenna and the target are enclosed in a box (picture one). In this way I bypass the problems of a large mesh.
In parallel I am also using another set up environment with only one box (picture two) to estimate the crosstalk between the two antennas.
After simulating the two hfss files I subtract the two frequency response to obtain the target one.
In time domain this means that I see an UWB impulse delayed by a constant as in a normal radar.
By simulating the structure with the distance of the ball variable I should see the radar attenuation but this is not happening.
The problem is that for a very low backscatter this process of subtracting has some error because the mesh in the two files are not the same.
So the question is how to reuse the mesh to overcome this problem??
Or other simpler solutions are very welcomed!
Cheers
Alex
