ECUACIÓN N BÁSICA B<br />

DE ALCANCE<br />

RADAR (2)<br />

• La potencia recibida será:<br />

Pr=[Pt/(4*<br />

/(4*π*R²)]*[Gt]*[σ/(4*π*R²)]*[Ae]<br />

=(Pt*Gt<br />

Pt*Gt* ó*Ae)/(4*<br />

)/(4*π*R²) ²<br />

• Cuando la potencia recibida sea igual a la<br />

mínima señal<br />

detectable(Smin) ) tendremos<br />

el alcance máximo m<br />

del radar:<br />

– Rmax=[(Pt*Gt*σ*Ae<br />

Ae)/(Smin*(4*<br />

)/(Smin*(4*π)²)]^¼
