Top 5 Combat Aircraft with Lowest Radar Cross section (RCS)

Radar cross-section (RCS), 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. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: the material … See more Informally, the RCS of an object is the cross-sectional area of a perfectly reflecting sphere that would produce the same strength reflection as would the object in question. (Bigger sizes of this imaginary sphere … See more The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. This does not equal geometric area. A perfectly conducting sphere of projected cross sectional area 1 m … See more RCS reduction is chiefly important in stealth technology for aircraft, missiles, ships, and other military vehicles. With smaller RCS, vehicles can better evade radar detection, … See more • System Planning Corporation • Electromagnetic modeling • Infrared signature • Survivability See more Size As a rule, the larger an object, the stronger its radar reflection and thus the greater its RCS.

WebThe RCS of known target geometries and their corresponding cross-section are shown in figure (7). The ideal standard to use is a conducting sphere of a known diameter. For … WebRadar cross-section is dominated by shape, because it's the shape that governs how much of the incident power is intercepted and sent back, as illustrated in the three examples below, where the objects are assumed to be large compared to the incident wavelength.

WebThe 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) where: • R = distance between radar and target • Webcross section becomes ˇa2 in the high-frequency limit. This physical feature of this plot is shown in Figure 34.5, and it also explains why the sky is not purple. 6Scattering cross …
