Improved method for embedded object detection and reconstruction through near-field pulse imaging techniques

A near-field imaging method for the detection, location, and reconstruction of an embedded object inside a given medium through the application of a frequency-synthesized near-field pulse in microwave range is described. This technique, called Single Probe Imaging through Detection and Reconstruction (SPIDR) method, employs a single near-field probe to identify, locate, and reconstruct an embedded object. The method focuses on measuring the reflected signal and the time delay associated with the distance between the pulse-generator source and the target. With a combination of two scan modes, called the planar and rotational scan, and a reconstruction software algorithm, the object’s outer form can be identified. The method is applicable to symmetrical objects which can be extended to non-symmetrical objects thorough enhanced reconstruction methods.
