Abstract :
This analysis develops an innovative image formation technique for reflection tomography based upon the extraction of multiple-bounce (MB) ghosting artifacts. The basic concept is that the time-of-flight between the transmission and reception of a waveform includes the realistic effects of MB interactions. An enhanced quality image can be constructed by utilizing only the single-bounce (SB) contributions of the measured phase history data. In addition, the MB ghosting artifacts are projected into a series of auxiliary images that can be applied to enhance the performance of object identification. These novel methods can be applied to the many domains of reflection tomography, including: (a) real aperture radar, (b) synthetic aperture radar (SAR), (c) inverse SAR (ISAR), (d) active sonar underwater acoustic mapping, (e) active geographic acoustic exploration, and (f) ultrasonic medical imaging.
