Implementations of Coherent Software-Defined Dual-Polarized Radars

Jeremy Hershberger; Thomas Pratt; Robert Kossler IEEE Transactions on Microwave Theory and Techniques, 2017

Software-defined radio (SDR) platforms represent a compelling solution for low-cost, flexible, dual-polarized radar systems. However, the phase coherency requirements of a dual-polarized radar system between the transmit ports and between the receive ports as well as between transmission and reception, are difficult to attain in popular SDRs. In this paper, we provide high-level overviews of SDR radar systems, dual-polarization radars, ...

In an X-band Cerenkov amplifier driven by a 0.8-MeV 6-kA electron beam, a gigawatt-level of power radiated in a Gaussian pattern in a 70-ns pulse duration has been demonstrated. The coherence of the output radiation is provided by dividing the oversized interaction space into separate sections with different azimuthal symmetry that couples only with the electron beam. A large gain ...

The paper details the implementation of multiple-symbols differential detection (MSDD) to differential cyclic delay diversity (DCDD) system. It is suggested that MSDD offers a better performance compared to normal differential detection.

Motion Segmentation by EM Clustering of Good Features

King Yuen Wong; M. E. Spetsakis 2004 Conference on Computer Vision and Pattern Recognition Workshop, 2004

We present a new algorithm that does motion segmentation by tracking small textured patches and then clustering them using EM. A small patch has the advantage that its motion is well modeled by uniform flow and runs a lower risk of boundary inclusion. Inherently, a small patch has less data so it is more susceptible to noise and it is ...

  • Advanced Digital Holographic Microscopy for Life Science Applications

    For the last decade Digital Holographic Microscopy (DHM) demonstrated his huge capabilities in many applications. In particular, it provides the refocusing of objects recorded out of focus and the quantitative phase contrast imaging. We implemented several types of DHM using optical sources of reduced coherence that largely improve the image quality by removing the coherent artifact noise. Different microscope implementations are described up to a color version with LED illumination allowing to record color holograms in snap shot mode. With respect to classical microscopy, DHM provides an enlarged amount of information on the sample under test that can be exploited to implement powerful processing as automated 3D detection and automated holographic classification. The developed automated processes have been applied to life sciences applications, as the water monitoring for environmental analysis and the dynamical behavior of red blood cells.

  • Tools for Deductive Databases

    Queries in deductive databases are expressed by pure Horn clauses following the principle of "say what you want and not how to get it." Consequently, there is a heavier burden on the compiler (or interpreter) to find an efficient evaluation of a given query. The difficulty is compounded when constraints (e.g., <) are present in rules or queries, or when the database has object-oriented features, which introduce function symbols. Research in the last decade has generated many ideas for efficient evaluation of queries. Gradually, these ideas have amalgamated into a smaller number of principles, but a complete coherence is still lacking. Some of these ideas and principles will be presented and compared while attempting to couch them in a coherent framework. In particular, the following will be discussed. • Magic sets vs. envelopes. • Query trees. • Removing redundant rules and subgoals. • Utilizing constraints most efficiently. • Detecting termination and effective computability in the presence of function symbols.

    Irradiance caching is a ray tracing-based technique for computing global illumination on diffuse surfaces. Specifically, it addresses the computation of indirect illumination bouncing off one diffuse object onto another. The sole purpose of irradiance caching is to make this computation reasonably fast. The main idea is to perform the indirect illumination sampling only at a selected set of locations in the scene, store the results in a cache, and reuse the cached value at other points through fast interpolation. This book is for anyone interested in making a production-ready implementation of irradiance caching that reliably renders artifact-free images. Since its invention 20 years ago, the irradiance caching algorithm has been successfully used to accelerate global illumination computation in the Radiance lighting simulation system. Its widespread use had to wait until computers became fast enough to consider global illumination in film production rendering. Since then, its use is biquitous. Virtually all commercial and open-source rendering software base the global illumination computation upon irradiance caching. Although elegant and powerful, the algorithm in its basic form often fails to produce artifact-free mages. Unfortunately, practical information on implementing the algorithm is scarce. The main objective of this book is to show the irradiance caching algorithm along with all the details and tricks upon which the success of its practical implementation is dependent. In addition, we discuss some extensions of the basic algorithm, such as a GPU implementation for interactive global illumination computation and temporal caching that exploits temporal coherence to suppress flickering in animations. Our goal is to show the material without being overly theoretical. However, the reader should have some basic understanding of rendering concepts, ray tracing in particular. Familiarity with global illumination is useful but not necessary to read this book.

  • Non-rigid point set registration: Coherent Point Drift

    We introduce Coherent Point Drift (CPD), a novel probabilistic method for nonrigid registration of point sets. The registration is treated as a Maximum Likelihood (ML) estimation problem with motion coherence constraint over the velocity field such that one point set moves coherently to align with the second set. We formulate the motion coherence constraint and derive a solution of regularized ML estimation through the variational approach, which leads to an elegant kernel form. We also derive the EM algorithm for the penalized ML optimization with deterministic annealing. The CPD method simultaneously finds both the non-rigid transformation and the correspondence between two point sets without making any prior assumption of the transformation model except that of motion coherence. This method can estimate complex non-linear non- rigid transformations, and is shown to be accurate on 2D and 3D examples and robust in the presence of outliers and missing points.
