Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. ... Though, for simple cases, the wavelength ranges of these two types of method overlap considerably, for difficult shapes and materials or very high accuracy they are combined in various sorts of hybrid … See more 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 … See more Size As a rule, the larger an object, the stronger its radar reflection and thus the greater its RCS. Also, radar of one band may not even detect certain size objects. For example, 10 cm (S-band radar) can detect rain drops but not clouds … See more Quantitatively, RCS is calculated in three-dimensions as Where See more For the case of an antenna the total RCS can be divided into two separate components as Structural Mode RCS and Antenna Mode RCS. The two components of the RCS relates to the two scattering phenomena that takes place at the antenna. When an … See more Informally, the RCS of an object is the cross-sectional area of a perfectly reflecting sphere that would produce the same strength … 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 … 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, whether it be from land-based installations, guided weapons or other vehicles. … See more

WebThe 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. … Web!The RCS in this case is simple: σ=0.2λ2 in square meters, where λ is the radar wavelength in meters. Often RCS is expressed in decibels above a square meter, termed dBsm, which is … ctbr6521cs
