Question

RCS of scattering object is defined as the ratio of _______

(a) Power density of signal scattered to power density of radio wave incident

(b) Power density of radio wave incident to power density of signal scattered

(c) Power density of incident waves to power density of reflected wave

(d) Power density of reflected wave to power density of incident waves

I have been asked this question in class test.

I'm obligated to ask this question of Scattering in portion Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Right answer is (a) Power density of signal scattered to power density of radio wave incident

The best I can explain: The radar cross section of a scattering object is defined as the ratio of the power density of the signal scattered in the direction of the receiver to the power density of the radio wave incident upon the scattering object. It has unit of square meters.
