Assisted living (AL) technologies, enabled by technical advances such as the advent of the
Internet of Things, are increasingly gaining importance in our aging society. This article …

Localization of objects is fast becoming a major aspect of wireless technologies, with
applications in logistics, surveillance, and emergency response. Time-of-arrival (TOA) …

Ranging from the theoretical basis of UWB sensors via implementation issues to
applications, this much-needed book bridges the gap between designers and appliers …

A compact dual-polarized antenna is described for ultrawideband (UWB) applications. The
main features of the antenna, besides an ultrawidebandwidth are low cross-polarization and …

In this paper, various positioning algorithms for range-based TOA and TDOA localization
have been analyzed, which include the Analytical method, Least Square method …

The term ultrawideband (UWB) describes a radar system with an effective signal bandwidth
that is a large percentage of the center frequency (20%–25%). This wide bandwidth gives …

Extracting snowpack parameters from snow cover on sea ice or land is a time-consuming
and potentially high-risk task. Moreover, deriving such parameters by manually digging a …

Ultrawideband (UWB) radar is a promising method for reliable remote monitoring of vital
signs. The use of multiple antennas at transmitter and receiver (MIMO) allows not only …

Modern radar systems are designed to have high Doppler tolerance to detect fast-moving
targets. This means range and Doppler estimations are inevitably coupled, opening …

Localization of persons that are hidden behind a corner is important in various security
situations when the first responders should not be exposed to any threat. This article …
