Data Rate Fingerprinting: A WLAN-Based Indoor Positioning Technique for Passive Localization

IEEE Sensors Journal, 2019
Received signal strength (RSS)/channel state information (CSI) fingerprinting techniques have been widely adopted for wireless local area network (WLAN)-based indoor localization.

A statistical approach to localize passive RFIDs

2006 IEEE International Symposium on Circuits and Systems, 2006
We suggest a novel method for localizing passive radio frequency identification (RFID) tags based on a Bayesian approach. The localization framework requires a suitable number of tag-readers deployed in the area under investigation and connected to antennas which, provided with rotation ability, perform the detection task by scanning each angular ...

A passive approach to sensor network localization

2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005
Sensor networks present the opportunity to accurately localize the phenomena of interest. To be able to do so however, sensor nodes, need themselves to be accurately localized. We present an algorithm to do this based on uncontrolled environmental sounds observed by each of the sensor nodes. A probabilistic generative model is presented and it is shown

Chorus: UWB Concurrent Transmissions for GPS-like Passive Localization of Countless Targets

International Symposium on Information Processing in Sensor Networks, 2019
We propose Chorus, a new ultra-wideband (UWB) localization scheme in which the target device computes the time difference of arrival (TDOA) of signals sent concurrently by localization anchors in known positions.

Passive localization algorithms

The Journal of the Acoustical Society of America, 2002
An acoustic source can be localized by exploiting the fact that, if the range is not too great, the wavefront of the incoming acoustic energy can be assumed to be circular. This is sometimes called ‘‘Wavefront Curvature Ranging.’’ Here, the estimation of range reduces to the estimation of the radius of a circle.

Emitter Localization Algorithm Based on Passive Synthetic Aperture

IEEE Transactions on Aerospace and Electronic Systems, 2022
Emitter localization is an active research topic in electronic reconnaissance. Recently, passive synthetic aperture (PSA) has been used to determine the azimuth and range distance of the emitter.

Multi-Sensor Passive Localization Based on Sensor Selection

Fusion, 2019
In passive localization applications, the positioning accuracy for an emitter is highly dependent on the geometry between sensors and the target, the site error and measurement noise of sensors.

Practical Passive Indoor Localization With Intelligent Reflecting Surface

IEEE Transactions on Mobile Computing
Intelligent reflecting surface has gained significant attention for supporting integrated sensing and communication (ISAC) by manipulating wireless signals. However, existing IRS-based sensing systems commonly utilize directional horn antennas for signal

Hansel: Distributed Localization in Passive Wireless Environments

2009 6th Annual IEEE Communications Society Conference on Sensor, Mesh and Ad Hoc Communications and Networks, 2009
This work presents a distributed routing protocol to help mobile users locate items in passive wireless environments. In these environments, a mobile user can detect items that are in its proximity, but items can not communicate directly with each other.
