RCS 단위

1. 송수신 레이다의 위치

Bistatic radar : radar tx. And rx. Are at different locations

Monostatic radar : tx. And rx. Are located o the same platform

Quasimonostatic : Two separated, slightly separated antennas

2. RCS 단위

RCS definition :

(클릭하면 제대로 보임)

Decibel unit of RCS : dBsm (decibels relative to a square meter)

σ in dBsm = 10log(σ in m²) = 10log(σ/m²)

 

dBsm = dBcm²-40 = dBmm²-60

dBλ²=10log(σ/λ²)= 10logσ-20logλ

 

Frequently it is convenient to specify dimension in terms of wavelength, rather than physical units such as meters.

example) 30dBλ² → ?dBsm
frequency : 3GHz = λ : 0.1m 인 경우
☞ 30dBλ² + 20logλ = (30-20) dBsm = 10 dBsm
