Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. [1] An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1] the material with which the target is made;

The Radar Cross Section σ (RCS) is an aircraft-specific quantity that depends on many factors. The computational determination of the RCS is only possible for simple bodies. The RCS of simple geometric bodies depends on the ratio of the structural dimensions of …

The radar cross section (RCS) of a target is the equivalent area seen by a radar. It is the fictitious area intercepting that amount of power which, when scattered equally in all directions, produces an echo at the radar equal to that from the target.

2019年8月27日 · The Radar Cross-Section of a target is the area that intercepts the radar's transmitted signals and reflects them back to the radar receiver. When a radar pulse is transmitted by a transmitter, it hits the target and gets scattered isotropically and only some part of it bounces back to the receiver.

Radar Cross Section (RCS) is a critical concept in radar systems and stealth technology. It refers to the measure of how detectable an object is by radar waves. Essentially, the larger the radar cross-section, the easier it is for radar systems to spot an object.

Radar Cross Section (RCS or σ ) is a measure of the energy that a radar target intercepts and scatters back toward the radar

Radar Cross Section (RCS) is the hypothetical area, that would intercept the incident power at the target, which if scattered isotropically, would produce the same echo power at the radar, as the actual target.

Radar cross section is the measure of a target's ability to reflect radar signals in the direction of the radar receiver, i.e. it is a measure of the ratio of backscatter power per steradian (unit solid angle) in the direction of the radar (from the target)

The radar cross section of an object exposed to a radar is a fictitious area that describes the intensity of the wave reflected back to the radar.

In Chapter 1, the term Radar Cross Section (RCS) was used to describe the amount of scattered power from a target towards the radar, when the target is illuminated by RF energy. At that time, RCS was referred to as a target-spe-cific constant. This was only a simplification and, in practice, it is rarely the case.
