What is RCS in fighter aircraft?

The radar cross section (RCS) of a target is defined as the effective area intercepting an amount of incident power which, when scattered isotropically, produces a level of reflected power at the radar equal to that from the target. …

In what conditions RCS is independent to the range?

The RCS of a sphere is independent of frequency if operating at sufficiently high frequencies where λ<.

Does radar detect wood?

Material. Materials such as metal are strongly radar reflective and tend to produce strong signals. Wood and cloth (such as portions of planes and balloons used to be commonly made) or plastic and fibreglass are less reflective or indeed transparent to radar making them suitable for radomes.

What are the part of RCS in radar?

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.

What determines the RCS of a radar target?

A target’s RCS depends on its size, reflectivity of its surface, and the directivity of the radar reflection caused by the target’s geometric shape. As a rule, the larger an object, the stronger its radar reflection and thus the greater its RCS.

How can the RCS of a stealth aircraft be reduced?

Modern stealth aircraft are said to have an RCS comparable with small birds or large insects, though this varies widely depending on aircraft and radar. If the RCS was directly related to the target’s cross-sectional area, the only way to reduce it would be to make the physical profile smaller.

How has radar evolved?

During the last sixty years Radar systems have evolved from auxiliary electronic devices to the heart of every modern weapon system on the ground, sea, air and space.

What determines the RCS of an aircraft?

The RCS of an aircraft depends on its aspect, the orientation of the target to the radar source. Any aircraft will have a smaller RCS from the front, and show-up bigger from the side or the rear. Looking at the table values, their numbers seem to be based on the frontal aspect, the lowest RCS of the aircraft.
