雷达散射截面 Radar cross-section
（重定向自Radar Cross Section）
雷达截面积（Radar cross-section，RCS）是指雷达的反射截面积，雷达探测的原理是发射电磁波照射到物体表面在反射回接收天线，而雷达波照射到物体表面物体表面依原路径返回的电磁波越少，雷达截面积越小，雷达对目标的信号特征就越小，探测距离也越短。

Radar cross-section (RCS) is a measure of how detectable an object is with a radar. A larger RCS indicates that an object is more easily detected.
An object reflects a limited amount of radar energy back to the source. The factors that influence this include:
- Absence of physical signs的意思
- Absence of placental secretion of chorionic gonadotrophin的意思
- Absence of postural sense的意思
- Absence of prepuce的意思
- Absence of pressure的意思
- absence of proable cause的意思
- absence of probable cause的意思
- Absence of prodrome的意思
- absence of proof的意思
- Absence of PTH的意思
- absence of pulmonary lobe的意思
- absence of pupil的意思
- absence of P wave的意思
- absence of radius的意思
- absence of reason的意思
- Absence of reflex的意思
- Absence of renin secretion的意思
- absence of restriction的意思
