Many geologic situations of interest to oil and gas exploration, and to enhanced recover methods, occur in media whose conductivity is too large to permit the use of pulsed GPRs because of severe dispersion. A continuous-wave radar is not affected by dispersion, and can use the round-trip phase, rather than time, to give an estimate of range. In this paper a range to target algorithms is developed for targets which exhibit a crude hyperbolic phase response. This new algorithm minimizes a difference function over both a 2n [pi]-phase interval and a wavelength interval to provide the range. Only crude initial estimates of the electrical parameters of the host media are required to initiate the algorithm. The furnished range may be the distance to some point within the target rather than to a point upon the illuminated surface because the target is three-dimensional and its electrical parameters can take on any value. This error can be reduced by a sufficiently high operating frequency. Examples are given for a variety of targets, media, range and operating frequency using simulated data.

The theory is developed for the antenna array for a proposed continuous-wave, ground-penetrating radar for use in a borehole, and field measurements are presented. Accomplishments include the underground measurement of the transmitting beam in the azimuth plane, active azimuth-steering of the transmitting beam, and the development of a range-to-target algorithm. The excellent performance of the antenna array supports the concept of a continuous-wave borehole radar. A field-prototype should be developed for use in both geothermal zones and for the exploration and recovery of oil and gas.

The Sixth Conference on Ultra-Wideband, Short-Pulse Electromagnetics (UWB SP6), chaired by Eric Mokole of the United States Naval Research Laboratory (NRL) and hosted by the NRL and the United States Naval Academy (USNA), was held at the USNA in Annapolis Maryland (USA) from 3-7 June 2002. UWB SP6 was part of the AMEREM 2002 Symposium, chaired by Terence Wieting of the NRL. AMEREM 2002 continued the series of international conferences that were held in: Brooklyn New York at the Polytechnic University in 1992 and 1994; Albuquerque New Mexico in 1996 as part of AMEREM '96; Tel-Aviv Israel in 1998 as part of EUROEM '98; and Edinburgh Scotland in 2000 as part of EUROEM 2000. The next conference (UWB SP7) will be held from 12-16 July 2004 at Otto von Guericke University in Magdeburg Germany (EUROEM 2004) and will be chaired by Frank Sabath. The purpose of these meetings is: to focus on advanced technologies for the generation, radiation, and detection of ultrawideband (UWB) short-pulse signals, taking into account their propagation about, scattering from, and coupling to targets and media of interest; to report on developments in supporting mathematical and numerical methods; and to describe current and potential future applications of the technology. The session topics of UWB-SP6 included electromagnetic theory, scattering, UWB antennas, UWB systems, ground penetrating radar (GPR), pulsed,. power generation, time-domain computational electromagnetics, UWB compatibility, target detection and discrimination, propagation through dispersive media, and wavelet and multi-resolution techniques.

This book deals with the basic theory for design and analysis of Low Probability of Intercept (LPI) radar systems. The design of one such multi-frequency high resolution LPI radar, PANDORA, is covered. This work represents the first time that the topic of multi-frequency radars is discussed in such detail and it is based on research conducted by the author in The Netherlands. The book provides the design tools needed for development, design, and analysis of high resolution radar systems for commercial as well as military applications. Software written in MATLAB and C++ is provided to guide the reader in calculating radar parameters and in ambiguity function analysis. Some radar simulation software is also included.
