What determines a greater Radar Cross Section (RCS) in radar terms?

• A. More energy reflected back toward the target
• B. Less energy reflected back toward the target
• C. Higher radar power
• D. A greater range to the radar

Answer: (A)

Radar Cross Section measures how much of the incoming energy is scattered back toward the radar. When more of that energy is reflected in the direction of the radar, the target presents a larger effective cross section, so the RCS is higher. The RCS itself is determined by the target’s shape, orientation, and surface properties, not by how powerful the radar is or how far away it is—the power and range affect how easy it is to detect that backscatter, but they don’t change the target’s RCS value. So, the key idea is that more energy returned toward the radar means a greater RCS.
