Summary:
Microwave imaging is being actively investigated for medical and process tomography. The formation of tomographic images from UWB signals is often problematic due to limitations arising from diffraction, reflection and refraction as well as attenuation. Many approaches to diffraction tomography rely on complex iterative approaches to solve the inverse problem of determining the object from scattered signals, or on some assumed foreknowledge of the dielectric of the environment / object being probed. Here we demonstrate both theoretically and experimentally how to apply a new method that achieves tomographic imaging without either of these problems. The method applies a forward propagation rather than back propagation and this requires no foreknowledge of the object’s properties or its environment.
