Talk Title: Distributed Sensing and Radio Frequency Tomography
Topics/Keywords: Radio Frequency, Remote and Close-In Sensing, Tomography, Spatial and Spectral Diversity, Congested Spectrum Environments, Signal and Image Processing
Many applications require imaging, shape reconstruction and material characterization of objects in the presence of interference, including concealed weapons through the wall sensing, below ground imaging, foliage penetration, and quality control in autonomous manufacturing. Recent advances in computational science and radio frequency (RF) technology improve the potential for successful applications of RF Tomography (RFT) to these challenging problems. RFT systems are supported by a variety of technologies, but they all share one common feature in that they all require viewing of the environment from a variety of angles or geometric diversity of illumination and observation. For applications where sensing occurs using electromagnetic waves, the most common is radar. Classical imaging systems employ a single aperture that is moved to form a synthetic aperture. However, numerous simultaneous fixed or moving apertures may be used. RFT typically employs a distributed system of low-cost, reconfigurable electromagnetic transmit and receive antennas placed somewhat arbitrarily around a region of interest. RFT transmitters radiate known waveforms, but sources of opportunity may also be exploited, while spatially distributed receivers sample scattered fields and relay this information to a central processor. The distinctive attribute of RFT is high resolution: sub-wavelength, range-independent, bandwidth-independent, resolution which is a function of the carrier frequency. This tutorial will present the principles of RFT, and the relationship between classical electromagnetics, signal processing, and applications specific phenomenology. This tutorial will include results from our most recent experiments in ground penetrating radar, and trends with many different applications such as the geolocation of passive RF tags in spectrally congested environments.

Dr. Wicks is a leading research scientist in remote sensing, signal processing and systems engineering, with a current focus on distributed sensing and radio frequency technology. He has pursued a variety of research interests in his career, including: radio frequency tomographic radar, counter explosive sensor technology, cognitive radar and radio, space object sensing, missile defense, deep earth probing radar, multi-dimensional adaptive processing for airborne and space based radar, ultra-wideband radio and radar, passive and active multi-static systems, and concealed weapons / contraband detection and carrier identification. He pioneered the concept of knowledge-based signal processing and waveform diversity, and has led national and international research teams on the design, development and fielding of novel algorithms, architectures and systems for remote sensing from space, air and surface platforms.
Research is currently focused on spatially and spectrally diverse sensing for the automatic detection, track, identification, and feature exploitation of obscured objects. The design and analysis of distributed radar for exoatmospheric surveillance is complimented by analysis and experiments for side-looking imaging and surface moving target indication radar. Recent research has resulted in the development of a mobile waveform diverse distributed MIMO radar system and a radio frequency tomography test bed at the University of Dayton. Research on integrated close-in sensing and long range wide area surveillance radar is addressing feature extraction, in addition to detection processing and track formation. Algorithms and architectures for the numerical and symbolic (heuristic) processing of sensor data is a primary focus of this research.
Dr. Wicks has published many papers, reports, book chapters, books and
