Seasonal Impact on 3D GPR Performance for Surveying Yedoma Ice Complex Deposits
Ground-penetrating radar (GPR) is a popular geophysical method for imaging subsurface structures with a resolution at decimeter scale, which is based on the emission, propagation, and reflection of electromagnetic waves. GPR surveys for imaging the cryosphere benefit from the typically highly resist...
