Abstract :
The application of a short-pulse, high-angular-resolution array focused in the near field for detection and imaging of shallow subsurface objects is discussed. An experimental system based on a forward-looking bistatic radar configuration with a digital synthetic aperture array receiver is described. Beam steering and scanning are accomplished using phase compensation based on simplified models of wave propagation across dielectric interfaces. Reconstructed images based on these models and utilizing real pulse-echo experimental data are included to demonstrate the performance of an L-band system
