摘要：

Monitoring corn fields with radar to measure soil moisture and biomass may yield benefits in corn cultivation. To do this, accurate forward models of corn backscatter are needed. Current models approximate the plant geometry with canonical shapes like cylinders and disks. Plant geometry and scattering may be accurately represented with 3D models and an appropriate electromagnetics solver. Using a finite-element method solver with periodic boundaries, qualitative agreement for corn backscatter is shown.
