It can be expressed by the following equation (1): σ0 total (dB) = σ0 veg + σ0 veg+soil + τ2 σ0 soil , For a given radar signal, σ0 from the bare soil has a linear function of the soil moisture with depth (0.0–7.5 cm) (Attema, E. and Ulaby, F.T. 1978) and σ0 veg+soil ≈ 0; therefore, eq. 1 can be modified as: σ0 total (dB) = σ0 veg + τ2 σ0 soil , where: σ0 veg (dB) = AV1 cos(1 τ2), τ2 = exp(2BV2 / cosθ), σ0 soil (dB) = C + D .	cache/hungeobull-2545.pdf	txt/hungeobull-2545.txt
