Abstract Details

2017, Doctor of Philosophy (Ph.D.), University of Dayton, Electro-Optics.
This research describes a multi-static interferometric synthetic aperture ladar (IFSAL) for high resolution, high precision 3D imaging. Code division multiple access apertures are implemented using periodic, pseudorandom noise waveforms to create spatial aperture diversity and overcome the ambiguity limitations associated with the aperture separation requirements for interferometric synthetic aperture ladar. The theory and basic design requirements are developed for mapping relative aperture phase to a high precision elevation profile in a sparse, multi-static IFSAL system and subsequent processing steps are developed. An analytic signal model and computer simulation is developed for baseline validation of the theory and processing techniques. This research also presents the first-of laboratory demonstration of a sparse, multi-static ladar for IFSAL imaging. A preliminary sensitivity analysis is developed, system limitations are addressed and design considerations are discussed.
