Abstract

The effects of rough surface scattering on the detection and imaging of objects are important in many applications including the imaging of objects on or near ocean surfaces and the detection of objects buried under ground rough surfaces. This paper focuses on the following problems: (1) Scattering from wedge-like rough surfaces representing ocean surfaces with sharp crested waves. (2) Scattering by objects above or below the rough surfaces. (3) UWB confocal imaging of objects near rough surfaces. Finite-Difference Time-Domain (FDTD) method is used to obtain frequency domain as well as time domain responses. Numerical simulations of various representative cases are conducted to understand and gain insight into the scattering effects on object detection and imaging.
