A Beam-splitting Approach to Measuring Microwave Backscattering Coefficient(σ°) and its Application

摘要：

This article attempts to use the beam-splitting approach to measure the microwave backscattering coefficient (σ°) of blank concrete samples,cobble surface samples of different sizes and others,and observe the variation laws of incident angle. This approach,low-cost and stable in performance,is able to overcome the cross talk between emitting and receiving antennas lying side by side,and result in the strict coincidence between incident beams and scattered ones. This approach and its results offer an experimental means of SAr remote sensing calibration and image interpretation.
