Radio frequency (RF) based indoor localisation techniques have gained much attention
over the past nearly three decades. Such techniques can be classified as active and passive …

Through-wall human sensing is of high interest for both military and nonmilitary applications,
including counter-terrorism and law enforcement purposes, particularly in the modern, highly …

In this paper, we consider a passive radar system that estimates the positions and velocities
of multiple moving targets by using OFDM signals transmitted by a totally un-coordinated …

We investigate indoor human multi-target tracking in cartesian coordinates based on range,
Doppler and Angle-of-Arrival measurements obtained with a four-antenna passive bistatic …

Passive radar network systems utilize multiple transmitters of opportunity and multichannel
receivers to offer remarkable performance improvement due to the advantage of signal and …

Device free activity recognition and monitoring has become a promising research area with
increasing public interest in pattern of life monitoring and chronic health conditions. This …

This paper introduces a Wi-Fi signal based passive wireless sensing system that has the
capability to detect diverse indoor human movements, from whole body motions to limb …

Building occupancy, which reflects occupant presence, movements and activities within the
building space, is a key factor to consider in building energy modelling and simulation …

In recent years, a number of studies have looked at the use of passive coherent location
(PCL) radar systems for short-range surveillance applications [1]-[8]. In such applications …

Non-contact devices for monitoring signs of life have attracted a lot of attention in recent
years for applications in security, emergency and disaster situations. Current devices …
