Equation:
Pr = ((Pp
x G2 x δ x
λ2) / ((4xpi)3 x r4))
= Watt |
| |
| Where: |
|
Pr
= power receiver input (Watt) |
| Pp
= peak RF power (Watt) |
| G
= antenna gain (figure) |
|
δ
= target Radar Cross Section (sq. m) |
|
λ
= wavelength (m) |
|
r
= target range (m) |

((1 000 000 x 10 000 000 x 1 x 0.008326562) /
(1984.4 x 2.7984121))
= 1.5-14
Watt or - 138 dBW
