Abstract: Various examples are provided related to penetrating radar based upon precursors. In one example, a method includes transmitting a radio frequency (RF) signal; and receiving a return signal associated with the RF signal, where the return signal is a precursor having no exponential decay. The precursor can be one of a sequence of precursors, which can be used to improve resolution of the system. The RF signal can be a short pulse generated by an RF front end, without automatic level control. The return signal can be processed without filtering.

Abstract: An exemplary focused tomography system comprises an x-ray transmitter that is configured to emit a radiation beam and an x-ray detector that is configured to detect incident radiation from the radiation beam. The system further includes an adaptive collimator device arranged between the x-ray transmitter and the x-ray detector and a controller device connected to the x-ray transmitter that is configured to cause the x-ray transmitter to emit the radiation beam at a first radiation dosage level when a path of the radiation beam intersects a region of interest of the subject and cause the x-ray transmitter to emit the radiation beam at a second radiation dosage level when the path of the radiation beam does not intersect the region of interest of the subject, such that the second radiation dosage level is less than the first radiation dosage level. Data within the region of interest can be reconstructed with image quality equivalent to traditional computed tomography scans.
