Equation:
Pd = ((Pp x G x Gr x
λ2)
/ ((4 x pi)2
x R2
x Lb x L)) x C |
| Where: |
|
Pd
|
= power density (Watt) |
|
Pp |
= RF peak power of BEACON transmitter (Watt) |
|
G |
= antenne gain of the transmitting antenna (figure) |
|
Gr |
= antenna gain of the receiving antenna (figure) |
| λ |
= wavelength (m) |
|
R |
= range to the BEACON receiver (m) |
|
Lb |
= losses of the BEACON transmitter (figure) |
| L |
= other losses (figure) |
|
C |
= correction factor (figure) |
