Radar cross section

Radar cross-section (RCS) is the measure of a target's ability to reflect radar signals in the direction of the radar receiver, i.e. it is a measure of the ratio of backscatter density in the direction of the radar (from the target) to the power density that is intercepted by the target 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 RCS (Radar Cross Section)란? 전자파가 물체에 닿은 후 발생한 반사파를 측정하는 기준 중 하나로서 단위는 평방미터 (m^2)를 사용하며, 정면 투영 단면적이 1m 2 인 완전 반사되는 금속 구체에 전자파를 방사하였을 때 반사파의 크기를 기준으로 실제 측정 대상의 물체가 갖는 RCS값을 산출한다. Radar는 특히 군사적인 목적으로 많이 활용 되고 있다 Radar cross section (RCS) is a characteristic of an object that indicates how much energy it reflects back towards a radar. RCS is used to evaluate how easily an object can be detected and tracked by a radar system From the quantum point view, the radar cross-section of oil spill cover and the clean sea is just quantum radar cross-section, which measures the rate of photon interaction with oil spill particles and ocean wave particles under the circumstance of perturbation concept, i.e., Bragg scattering

Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver Radar cross section is one of the key parameters in the detection of targets. It is used to describe the amount of scattered power from a target towards the radar. In stealth design of aircrafts and sea vessels, it is required to maintain low RCS. Lower the RCS, lower is the detectability and vice versa. I

Radar cross section (RCS) is a measure of the electromagnetic energy intercepted and reradiated at the same wavelength by any object. The dimensions are those of an area, usually square meters. The object of interest is compared to an idealized object that is large with respect to a wavelength, has an intercept area of one square unit, is perfectly conducting, and reradiates isotropically Radar Cross Section (RCS) of corner reflectors plays a major role for estimation of calibration parameters and hence sigma naught of the target in the radar image. 3.1 Radar Cross Section of Corner Reflectors Radar scattering is typically represented as the radar cross section.
