Research Topics


The main objectives of this proposed phase II research program include two major components. The first is to continue the advancements of high-performance image reconstruction and target recognition techniques based on the backward algorithm. The phase I theoretical results show the backward propagation algorithm to have consistent performance in terms of resolution limit, sensitivity, and computational structures across a variety of system configurations, aperture shapes, and illumination waveforms. In particular, phase I demonstrated the near-field imaging abilities of the algorithm with an experimental data set provided by Naval Air Warfare Center at Chinalake. Based on these successes we plan to continue the development of the algorithm by further investigating parallel implementation optimizations and performing additional tests with experimental and simulated data. The second objective of this program is to develop a software package which implements the backward propagation algorithm and is suitable for commercial applications. This requires coding the core reconstruction code in a modular and efficient way to promote reusability to support future related applications. A complete suite of support software will also be developed to support visualization, data storage and retrieval, and interfacing with common data formats.
