10 Questions
What happens to electromagnetic waves when incident on a target?
They are diffracted or scattered in all directions
What are the two parts into which the scattered waves are broken down?
Waves with the same polarization as the receiving antenna and waves with different polarization
What is the Principal Polarization (PP) in radar cross section (RCS)?
The waves with the same polarization as the receiving antenna
What is the target RCS defined as?
The intensity of the back-scattered energy with the same polarization as the radar’s receiving antenna
What happens when a target is illuminated by RF energy?
It acts in a certain way
What is the target RCS defined as?
The intensity of the back-scattered energy that has the same polarization as the radar’s receiving antenna
What are the two polarizations referred to in radar cross section (RCS)?
Principal Polarization (PP) and Orthogonal Polarization (OP)
What happens to the scattered waves with different polarization than the radar’s receiving antenna?
They have a different polarization to which the receiving antenna does not respond
What type of wavefronts are decomposed into a linear combination of plane waves in the far field?
Spherical waves
What does a target act like when illuminated by RF energy?
A virtual antenna
