In this paper, time delay estimation using the maximum likelihood principle is addressed for the multipath exploitation problem, and the corresponding Cramér-Rao bounds are derived. A single wideband radar, and a target in a known reflecting geometry are assumed. If the multipath is indeed detectable and resolvable, it is shown here that multipath… (More)

Radio frequency (RF) tomography is proposed to detect underground voids, such as tunnels or caches, over relatively wide areas of regard. The RF tomography approach requires a set of low-cost transmitters and receivers arbitrarily deployed on the surface of the ground or slightly buried. Using the principles of inverse scattering and diffraction tomography,… (More)

We present an approach to performing rapid calculations of temperature within tissue by interleaving, at regular time intervals, 1) an analytical solution to the Pennes (or other desired) bioheat equation excluding the term for thermal conduction and 2) application of a spatial filter to approximate the effects of thermal conduction. Here, the basic… (More)

Three extensions to radio-frequency (RF) tomography for imaging of voids under wide areas of regard are presented. These extensions are motivated by three challenges. One challenge is the lateral wave, which propagates in proximity of the air–earth interface and represents the predominant radiation mechanism for wide-area surveillance, sensing of denied… (More)

Radio-frequency (RF) tomography is extended for imaging underground structures and tunnels assuming rough terrain. The theory of RF tomography described in an earlier paper remains applicable, provided that a numerical Green’s function is computed. An FFT-based and intrinsically parallel method for obtaining numerical Green’s functions is described. This… (More)

The increasing demand for wireless ubiquitous services necessitates new spectrum allotments or a re-design of current systems to effectively manage coexistence between different types of technologies. In particular, the S-band (2-4 GHz) is in high demand for both surveillance and weather radar, communication satellites and commercial wireless networks. In… (More)

We present a six-dimensional distributed vector sensor for Direction of Arrival estimation applications. A vector sensor should measure all 6 components of the electromagnetic field at the same location. Such sensor is motivated by recent analytical results, showing an improved estimation of the direction of arrival of the signal from a single source. Since… (More)

Multipath is exploited to image targets that are hidden due to lack of line of sight (LOS) path in urban environments. Urban radar scenes include building walls, therefore creating reflections causing multipath returns. Conventional processing via synthetic aperture beamforming algorithms do not detect or localize the target at its true position. To remove… (More)

An overview of the challenges related to spectrum sharing between radar and communication systems is provided and some potential ways to address them are indicated.

Distributed Radio Frequency (RF) Tomography is a novel approach for detecting underground tunnels and caves, over relatively wide areas. This method requires a set of affordable transmitters and receivers randomly deployed above the ground. Using the principles of inverse scattering, it is possible to develop a simplified theory for imaging below ground,… (More)
