Wi‐Fi technology has strong potentials in indoor and outdoor sensing applications; it has
several important features which makes it an appealing option compared to other sensing …

In this paper, we investigate the feasibility of uncooperatively and covertly detecting people
moving behind walls using passive bistatic WiFi radar at standoff distances. A series of …

The practical feasibility of a WiFi transmissions based passive bistatic radar (PBR) is
analyzed here. The required data processing steps are described including the adopted …

The idea for this volume originated at the Rutgers School of Criminal Justice. I came to the
school in the fall of 2006 after completing my Biochemistry and Molecular Biophysics …

Device-free localization systems, such as variance-based radio tomographic imaging
(VRTI), use received signal strength (RSS) variations caused by human motion in a static …

Occupancy detection and people counting technologies have important uses in many
scenarios ranging from management of human resources, optimising energy use in …

Current smartphone inputs are limited to physical buttons, touchscreens, cameras or built-in
sensors. These approaches either require a dedicated surface or line-of-sight for interaction …

Wireless transmission is becoming an increasingly widely available source of transmissions
for passive radar detection. In this paper, we present a detailed analysis of the ambiguity …

A new approach to the passive coherent location (PCL) signal processing technique
dedicated for use on mobile radar platforms is presented. The main goal of the research …

The design and implementation of a real-time passive high Doppler resolution radar system
is described in this paper. Batch processing and pipelined processing flow are introduced …
