Bistatic Radar Configuration for Soil Moisture Retrieval: Analysis of the Spatial Coverage
Some outcomes of a feasibility analysis of a spaceborne bistatic radar mission for soil moisture retrieval are presented in this paper. The study starts from the orbital design of the configuration suitable for soil moisture estimation identified in a previous study. This configuration is refined according to the results of an analysis of the spatial resolution. The paper focuses on the assessm...
متن کاملSoil Moisture Retrieval Using Data Cube Representation of Radar Scattering
A time-series algorithm is proposed to retrieve surface (from surface down to 1 m depth) soil moisture using the simulated radar data. The time-series approach uses co-polarized (V V and HH) backscattering coefficient (σ) values. Temporal averaging is applied to reduce the radar measurement noise. To the extent that the surface roughness does not change within the time-series window, the reduct...
متن کاملSeasonal Polarimetric Measurements of Soil Moisture Using Tower-Based GPS Bistatic Radar
The results of GPS L-band (L1, = 19 cm) surface reflection measurements observed using multiple polarizations and receiving antenna gains are described. The measurements were performed using the 300-m tall ETL Boulder Atmospheric Observatory (BAO) tower during summer through fall of 2002. In this experiment the first seasonal measurements of bare soil moisture from a stationary location using b...
متن کاملSupport Vector Regression for Retrieval of Soil Moisture Using Bistatic Scatterometer Data at X-Band
An approach was evaluated for the retrieval of soil moisture of bare soil surface using bistatic scatterometer data in the angular range of 200 to 700 at VVand HHpolarization. The microwave data was acquired by specially designed X-band (10 GHz) bistatic scatterometer. The linear regression analysis was done between scattering coefficients and soil moisture content to select the suitable incide...
