radar cross section (RCS)

radar cross section (RCS)
Radar cross section of a combat aircraft from various angles. It looks bigger from directly below or directly from the top than in a turn. It is the least when viewed directly from the front or the rear and is maximum when viewed from either side.
The measure of reflectivity of the received radar signals by an aircraft, it is expressed as square meters (m2). It is dependent on the true size, range, aspect, geometric shape, materials, surface texture, and other properties of the target aircraft. The most important element is the target aspect [i.e., the area normal (perpendicular) to the radar axis]. The higher the area, the greater the RCS.

The structural and mechanical components are fabricated from a wide selection of material systems from basic steel construction to advanced material systems that not only provide structural components, but also provide acoustic, thermal, radar cross-section and electrical solutions.
The A-12, with a combination of Mach 3 cruise and an exceptionally low radar cross-section (RCS), was designed to be invulnerable to SAM attack.
The superstructure arrangement is designed to minimise radar cross-section.
These included unmanned pilot training, radar cross-section measurements, ground station system integration and, in April 2013, taxi trials on the runway at Warton.
The two prototypes developed by Zhejiang University, if practically implemented, can be used to design a new-generation of stealth fighter aircrafts, capable of evading heat-seeking missiles, and also boast reduced the Radar Cross-Section (RCS) to become truly invisible in the sky.
Perhaps the most important characteristic of the F-35 is the stealth technology used to limit the radar cross-section of the plane.
In terms of construction, the Blohm + Voss Braunschweig ships use an angular design masking the superstructure to reduce radar cross-section, a precaution that is further enhanced by a lack of topside clutter and an enclosed bridge.
Incorporates an asymptotic solver based on the Shooting Bouncing Ray method, an extension to physical optics, capable of tackling simulations with an electric size of many thousands of wavelengths such as radar cross-section analysis.
The Silent Eagle configuration includes 15-degree outward-canted V-tails - a shift away from the characteristic vertical fins of the F-15 that reduces the radar cross-section.
Using radar cross-section (RCS) reduction techniques, the ship will not only have a new look, but will be more diffi cult to locate and target.
