减缩天线的雷达散射截面积(Radar Cross Section )一 雷达散射截面积(RCS)是电磁隐身技术中的一项重要指标。它直接反映了目标物能否被雷达探测到的可能性。RCS的计算,可以粗略得认为是由于目标物的存在而反射回雷达所在位置的电磁波的能量与雷达发射出的电磁波能量的比值。根据定义不难发现,RCS值越低代表目标物越难被...

在频域中,用来描述散射体电磁散射能力大小的物理量为目标的雷达散射截面或雷达截面,英文为 Radar Cross Section(RCS)。 雷达散射截面的物理含义 当物体被电磁波照射时,被物体截获的能量将向各个方向散射,散射场与入射场之和就构成了空间总场。 从射线的角度看,散射场包括了因介质波阻抗突变而在物体表面上产生的反射,...

典型目标雷达散射截面(Radar cross section,RCS)~ 首先要说明的是,现役隐身战机的RCS,基本是保密的。不同方位角的数值也会有极大差异。因此,我们所了解的大部分RCS都是估计或者猜测,未必就准确。不同途径/...

Radar Cross Section (RCS) is defined as the ratio of the power scattered back to the radar receiver over the incident radar power density per unit of solid angle on the target, taking into account the distance between the radar and the target, frequency, polarization, and composition of the...
Abstract 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...
In radar systems, the amount of energy reflected from a target is determined by the radar cross section (RCS), defined as where represents the RCS, is the distance between the radar and the target, is the field strength of the signal reflected from the target, and is the field strength ...
Radar Cross Section In subject area: Computer Science Radar Cross Section (RCS) refers to the equivalent area of a target that is visible to a radar system, determining the amount of power scattered back to the radar. It is influenced by the target's geometry, aspect angle, frequency, and...
