What is a "Radar Cross Section Reduction"? The Most Authoritative Explanation.

What are the techniques for radar cross section reduction?

As far as radar signature is concerned, there are four basic techniques for radar cross section reduction (RCSR); shaping, radar absorbing materials, passive cancellation and active cancellation. Of the four, the use of shaping and radar absorbers are the most effective.

What is radar cross section (RCS)?

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 body to the wavelength. the electrical properties of the target's surface.

What is the radar cross section of a target?

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. Mathematically, it is written as: (10.8) σ = lim R → ∞ 4 π R 2 | E s | 2 | E i | 2,

What is the relative radar cross section of a b 26 aircraft?

Figure 1: Experimentally determined relative radar cross section σ /σ 0 of a B 26 aircraft at a frequency of 3 GHz (after Skolnik). 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.
