Microwave response to broad leaf vegetation (spinach) and vegetation covered moist soil for remote sensing

Abstract

Soil moisture is one of the most important parameter which controls the growth of the vegetation. For accurate data and sufficient information to increase food production, remote sensing technique is highly useful. This paper deals with the bistatic microwave response of spinach and spinach covered soil moisture at various growth stages on X-band of the frequency spectrum. The microwave response of spinach in different stages of growth have been studied in terms of scattering co-efficient (σ°). The look angle effect on σ is observed for like polarization i.e. (VV-and-HH) only. A linear regression analysis has been done between the vegetation covered soil moisture and scattering co-efficient. It provides an idea that VV-polarization is more sensitive than HH-polarization for vegetation covered soil moisture and best suitable look angle for observing vegetation covered soil moisture is less than 40°(θ<40°).
