Book Description
With the emergence of compressive sensing and sparse signal reconstruction, approaches to urban radar have shifted toward relaxed constraints on signal sampling schemes in time and space, and to effectively address logistic difficulties in data acquisition. Traditionally, these challenges have hindered high resolution imaging by restricting both bandwidth and aperture, and by imposing uniformity and bounds on sampling rates. Compressive Sensing for Urban Radar is the first book to focus on a hybrid of two key areas: compressive sensing and urban sensing. It explains how reliable imaging, tracking, and localization of indoor targets can be achieved using compressed observations that amount to a tiny percentage of the entire data volume. Capturing the latest and most important advances in the field, this state-of-the-art text: Covers both ground-based and airborne synthetic aperture radar (SAR) and uses different signal waveforms Demonstrates successful applications of compressive sensing for target detection and revealing building interiors Describes problems facing urban radar and highlights sparse reconstruction techniques applicable to urban environments Deals with both stationary and moving indoor targets in the presence of wall clutter and multipath exploitation Provides numerous supporting examples using real data and computational electromagnetic modeling Featuring 13 chapters written by leading researchers and experts, Compressive Sensing for Urban Radar is a useful and authoritative reference for radar engineers and defense contractors, as well as a seminal work for graduate students and academia.

Book Description
Compressed Sensing (CS) theory is a novel signal processing paradigm, which states that sparse signals of interest can be accurately recovered from a small set of linear measurements using efficient L1-norm minimization techniques. CS theory has been successfully applied to many sensing applications; such has optical imaging, X-ray CT, and Magnetic Resonance Imaging (MRI). However, there are two critical deficiencies in how CS theory is applied to these practical sensing applications. First, the most common reconstruction algorithms ignore the constraints placed on the recovered variable by the laws of physics. Second, the measurement system must be constructed deterministically, and so it is not possible to utilize random matrix theory to assess the CS reconstruction capabilities of the sensing matrix. In this thesis, we propose solutions to these two deficiencies in the context of electromagnetic imaging applications, in which the unknown variables are related to the dielectric constant and conductivity of the scatterers. First, we introduce a set of novel Physicality Constrained Compressed Sensing (PCCS) optimization programs, which augment the standard CS optimization programs to force the resulting variables to obey the laws of physics. The PCCS problems are investigated from both theoretical and practical stand-points, as well as in the context of a hybrid Digital Breast Tomosynthesis (DBT) / Nearfield Radar Imaging (NRI) system for breast cancer detection. Our analysis shows how the PCCS problems provide enhanced recovery capabilities over the standard CS problems. We also describe three efficient algorithms for solving the PCCS optimization programs. Second, we present a novel numerical optimization method for designing so-called "compressive antennas" with enhanced CS recovery capabilities. In this method, the constitutive parameters of scatterers placed along a traditional antenna are designed in order to maximize the capacity of the sensing matrix. Through a theoretical analysis and a series of numerical examples, we demonstrate the ability of the optimization method to design antenna configurations with enhanced CS recovery capabilities. Finally, we briefly discuss an extension of the design method to Multiple Input Multiple Output (MIMO) communication systems.

Book Description
The objective of this book is to provide the reader with a comprehensive survey of the topic compressed sensing in information retrieval and signal detection with privacy preserving functionality without compromising the performance of the embedding in terms of accuracy or computational efficiency. The reader is guided in exploring the topic by first establishing a shared knowledge about compressed sensing and how it is used nowadays. Then, clear models and definitions for its use as a cryptosystem and a privacy-preserving embedding are laid down, before tackling state-of-the-art results for both applications. The reader will conclude the book having learned that the current results in terms of security of compressed techniques allow it to be a very promising solution to many practical problems of interest. The book caters to a broad audience among researchers, scientists, or engineers with very diverse backgrounds, having interests in security, cryptography and privacy in information retrieval systems. Accompanying software is made available on the authors’ website to reproduce the experiments and techniques presented in the book. The only background required to the reader is a good knowledge of linear algebra, probability and information theory.

Book Description
In this project we expanded the field of compressive sensing in both theoretical and practical ways. We first demonstrated the information scalability of CS. We applied CS principles to analog-to-digital conversion, showing ADC can be accomplished on structured high rate signals with sub-Nyquist sampling. We introduced a smashed filter to perform statistical classification problems with a rate of measurements that corresponds to the problem structure, rather than bandwidth. Second, we improved on previous work in distributed compressive sensing. We used graphical models to derive performance bounds on multi-sensor settings. Finally, we created a CS-based radar framework and applied it to both 1-D ranging and 2-D synthetic aperture problems.

Book Description
Efficiency and robustness are often the main concerns in model design and algorithm development. Nowadays a lot of algorithms have been proposed with emphasis on one or the other. This thesis provides several algorithms together with their applications to address these two needs. The first part of the thesis discusses the efficiency concern in video compression and reconstruction. With the increasing demand in real-time data transmission and storage, these two problems are attracting more and more attention. In terms of video compression, classic models often use a fixed temporal compression rate, while there are many potential gains in developing systems and procedures incorporating adaptive temporal compression rate. In Chapter 2, an algorithm based on local patches and polynomial fitting is proposed to adaptively predicts the temporal compression rate given the behavior of a few previous compressed frames. As for the inverse model, Chapter 3 presents a fast total variation based method for reconstructing video compressive sensing data. The regularization in the model is imposed on both the spatial and temporal components, which provides a more consistent approximation of the connection between neighboring frames with little to no increase in model complexity. The second part of the thesis covers a new technique named adaptive outlier pursuit for handling sparsely corrupted data. In many real world applications, noise is often unavoidable during data acquisition and transmission. Some noise can damage part of the data seriously and make it contain no useful information at all. Algorithms robust to this type of noise are strongly needed. The technique adaptive outlier pursuit is introduced to deal with outliers in the acquired measurements. Instead of detecting and removing the outliers before applying classic algorithms, it alternates between the outlier detection and the signal reconstruction task, hence iteratively approaches the true signal in a more accurate way. It is applied to robust 1-bit compressive sensing and exact matrix completion in Chapter 5 and Chapter 6 respectively.
