High-Dimensional Information Detection based on Correlation Imaging Theory

Radar is a device that uses electromagnetic(EM) waves to detect targets; it can measure the position parameters and motion parameters and extract target characteristics information by analyzing the reflected signal from the target. From the perspective of the radar theoretical basis of physics, the more than 70 years of development of radar are based on the EM field fluctuation theory of physics. Many theories have been developed towards one-dimensional signal processing. For example, a variety of threshold filtering have widely used as methods to resist interference during detection. The optimal state estimation describes the propagation process of the statistical characteristics of the target over time in the probability domain. Compressed sensing greatly improves the reconstructing efficiency of the sparse signal. These theories are one-dimensional information processing. The information obtained by them is a deterministic description of the EM field. The correlated imaging technique is from the high-order coherence property of the EM field, which uses the fluctuation characteristic of the EM field to realize non-local imaging. Correlated imaging radar, a combination of correlated imaging techniques and modern information theory, will provide a novel remote sensing detection and imaging method. More importantly, correlated imaging radar is a new research field. Therefore, a complete theoretical frame and application system should be urgently built up and improved. Based on the coherence theory of the EM field, the work in this thesis explores the method of determining the statistical characteristics of the EM field so that the high dimensional target information can be detected, including theoretical analysis, principle design, imaging modes, target detecting models, image reconstruction algorithms, the enhancement of visibility, and system design. The simulations and real experiments are set up to prove the theory's validity and the systems' feasibility

Recent Advances in Forensic Anthropological Methods and Research

Forensic anthropology, while still relatively in its infancy compared to other forensic science disciplines, adopts a wide array of methods from many disciplines for human skeletal identification in medico-legal and humanitarian contexts. The human skeleton is a dynamic tissue that can withstand the ravages of time given the right environment and may be the only remaining evidence left in a forensic case whether a week or decades old. Improved understanding of the intrinsic and extrinsic factors that modulate skeletal tissues allows researchers and practitioners to improve the accuracy and precision of identification methods ranging from establishing a biological profile such as estimating age-at-death, and population affinity, estimating time-since-death, using isotopes for geolocation of unidentified decedents, radiology for personal identification, histology to assess a live birth, to assessing traumatic injuries and so much more
