Cramer-Rao Lower Bound Derivation and Performance Analysis for Space-Based SAR SMTI
This thesis develops the Cram ́er-Rao Lower Bound (CRLB) for multi-channel space- borne synthetic aperture radar (SAR) system and provides surface moving target in- dication (SMTI) performance analysis. A multi-channel moving target signal model is derived in satellite earth-fixed earth-centered …

Sampling in Computational Cameras
<p>This dissertation contributes to computational imaging by studying the intersection of sampling and artificial intelligence (AI). It has been demonstrated that AI shows superior performance in various image processing problems, ranging from super- resolution to classification. In this work we …

Received Signal Strength-Based Localization of Non-Collaborative Emitters in the Presence of Correlated Shadowing
… the position of a non-collaborative emitter using a network of collaborative sensors. This paper examines RSS-based localization and differential RSS (DRSS) localization in the presence of correlated shadowing with no knowledge of the emitter's reference power. A new non-linear least …

Towards high-resolution magnetic resonance spectroscopic imaging: spatiotemporal denoising and echo-time selection
… additional spectral information provides a powerful tool for in vivo study of biological tissues. However, considerable practical challenges, which cannot be overcome using the traditional Fourier method, remain in obtaining spatial-spectral data with both high resolution and high …

Optimizing range aware localization in wireless sensor networks (WSNs)
… of wireless sensor networks (WSNs) in numerous emerging applications have prevailed us to realize that smart living is no longer an imagination, it already exists. In emerging applications, localization is an essential function so that all the sensed information can be responded carefully. …

GSM based Communication-Sensor (CommSense) System
… has been a major area of research in radar engineering. In the recent years, due to the widely available wireless signals, a new area of research called commensal radars has emerged. Commensal radars use available wireless Radio Frequency (RF) signals to detect and track targets of interest. This …
