MATLAB: Do bistatic radar simulations require antenna elements that support polarization

Question

I am interested in simulating a bistatic radar system.

I noticed that a short dipole antenna element is used in the 

Simulating a Bistatic Polarimetric Radar

example at the link below. Is it always the case that I will need to use an antenna element that supports polarization for bistatic radar simulations?

Answer 1

As of R2020b, polarization encapsulates reflected signals and is necessary for the bistatic radar simulation workflow.

However, in some instances, the same simulation results can be achieved without polarization (using isotropic antenna elements). For example, for a simulation involving constant radar cross sections, a non-polarized radar target can be used as an alternative.
