Radar Tomography of Moving Targets

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to Department of Defense, Washington Headquarters Services, Directorate for Information Operations and Reports (0704-0188), 1215 Jefferson Davis Highway, Suite 1204, Arlington, VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.

Waveform design for low frequency tomography

“…Three-dimensional (monostatic) imaging using tomographic images is directly addressed in [13], combined with ultra wideband waveforms, in this case a Gaussian pulse, though with a circular SAR sampling trajectory. In this paper particular attention was paid to the weighting aspects of filtered back projection More recently there has been a substantial body of tomographic work both sponsored and conducted by the U. S. Air Force Research Laboratory [14][15][16][17][18][19][20][21]. In [14] Griffiths, Baker and Coetzee investigate tomography in an ISAR context, extending this to tomography against moving targets [15].…”

Ultra-narrowband attributes of spatially and spectrally sparse tomography are explored in [16][17][18][19][20][21][22] as applied to the very difficult problem of detecting tunnels and hard and deeply buried targets.…”
