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 broadband Frequency Modulated Continuous Wave (FMCW) radar has become the dominant technology for automotive use because it combines high resolution in range and depth perception, with the detection of objects like pedestrians and bicycles in a small radar cross-section.
The inward-angled twin fins over the engines and the pointed engine cones also decreased the Black Bird's radar cross-section.
These, alongside planned mission maneuvers, reduce an aircraft's radar cross-section (reflection of radar signals).
It said, "The aircraft does appear to mount an electro-optical /infrared sensor turret under the nose--but the camera would simply add to the F-313's radar cross-section," meaning it would be readily visible to radar and not stealthy,
Dehqan explained that Sayyad 2 is a missile for mid-range and high-altitude air defense systems, designed based on the state-of-the-art technologies which can destroy different types of helicopters, drones and targets with small radar cross-section and high speed and maneuverability within its operational range.
Periodic maintenance is required to maintain the special exterior coatings that contribute to the 5th Generation Raptor's Very Low Observable (VLO) radar cross-section.
Most importantly, we didn't learn much about its radar cross-section.
A new chaff material with better dispersion or radar cross-section could enhance the capability of UK armed forces to counter radar threats to air and naval platforms.
Traditionally conformal tanks can be added and removed with relative ease, so having the option to mount them at the cost of increased radar cross-section is an enticing arrow for Israel to have on its quiver.
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.
