RCS Calculation

Compatibility:

Consider figure 21, which depicts an observation point FDTD - Equation1in the far field many
wavelengths away from the near field path FDTD - Equation2. In this case, the Far Field
can be identified as:

FDTD - Equation 81

for TE simulation and

FDTD - Equation 82

for TM simulation.

Then the bistatic radar cross section (RCS) in two dimension can be defined as:

FDTD - Equation 83
