| 요약 | It is of importance to understand the physics as electromagnetic (EM) waves propagate through stratified media, are scattered back from buried irregularities, and are received by an antenna in the near field. To generate better images, we need t |
| 요약 | To form real-time continuous images of targets embedded in a layered structure, a near-field uniform diffraction tomographic (UDT) imaging algorithm is developed. Conventional diffraction tomography (DT) improperly applies the stationary phase m |
| 요약 | To overcome the singularity problem caused by nulls in the antenna gain pattern in DT and UDT, a fast back-projection (FBP) imaging algorithm is propose to provide balanced monostatic and bistatic images, where both the stationary phase method a |
| 요약 | After constructing a radar image, it is of interest to quantify buried target parameters, such as the shape, location, orientation, and size. These parameters can be estimated by the implementation of the spatial moment method. However, due to t |
| 요약 | Lastly, it has been shown that the interface between the external region and a dense medium tends to focus the energy from the antenna straight into the medium due to refraction, losing important wide-angle illumination of embedded objects. This |
