On Indoor Human Sensing using Commodity Radar

Radio frequency radar indoors is gaining traction owing to its promise for extended coverage and device-free operation. However, while the well-behaved radar sensing model affords clear advantages, the cluttered indoor environment presents numerous challenges for reliable human sensing. Classic radar techniques are hard to call upon since the kinematic and clutter behaviours in aerospace are vastly different from their indoor counterparts. We demonstrate the peculiarities of indoor radar using a commercial 2D array commodity device in the 6 to 8.5 GHz band. We then present a set of processing tools suited for indoor radar human sensing. We show that excessive indoor clutter and erratic human kinematics can be largely mitigated building on such processing tools without resorting to much low-level techniques unsupported by commercial commodity radars.

© 1963-2012 IEEE. This article presents a packaged SiGe BiCMOS reflectometer for 0.01-26-GHz two-port vector network analyzers (VNAs). The reflectometer chip is composed of a resistive bridge coupler and two wideband heterodyne receivers for coherent magnitude and phase detection. In addition, a high-linearity receiver channel is designed to accommodate 20 ...

Protecting photonic quantum states using topology

  • Blanco-Redondo A.

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

  • Saniee I.
  • Weldon M.

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...
