Subarray processing for passive radar localization

2017 IEEE Radar Conference (RadarConf), 2017
The addition of an array to a passive radar increases the possible ways to process data for different purposes. The digital beamforming capability, used in a passive radar environment with multiple transmitters and geometries, can be used to increase gain in a particular direction, reduce signal interference in another, or to estimate the direction of ...

Scan-based emitter passive localization

IEEE Transactions on Aerospace and Electronic Systems, 2007
This paper investigates the problem of estimating the position of a scanning emitter using a passive scan-based geolocation technique. This is achieved by taking advantage of the geometric constraints introduced by the uniform rotating motion of the antenna main beam as it sweeps across a number of separate receivers.

Localization Systems Using Passive UHF RFID

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
Since gathering spatial information of objects often provides a large number of extended functions in RFID based applications, many different localization systems have been developed in recent years. Determining and estimating the physical location of tagged objects in an interrogating area is known as localization.

Array based passive radar target localization

2016 IEEE Radar Conference (RadarConf), 2016
In this paper, a procedure for target localization with digital television based passive radar is developed. Considerations for beamforming, including array calibration and range-Doppler processing are presented, which establish a comprehensive framework for determining the 3D position of a target in space.

Challenges of passive infrared indoor localization

2008 5th Workshop on Positioning, Navigation and Communication, 2008
In this paper a new approach for locating people indoors is proposed. Since location based services become relevant for an increasing number of people, e. g. the location dependent automatic control of lighting, there is a need for unobtrusive and easy to use location systems.

UAV Path Planning for Passive Emitter Localization

IEEE Transactions on Aerospace and Electronic Systems, 2012
A path planning algorithm is presented for uninhabited aerial vehicles (UAVs) trying to geolocate an emitter using passive payload sensors. The objective is to generate a sequence of waypoints for each vehicle that minimizes localization uncertainty.

Indoor localization with passive sensors

2013
In this thesis, a framework is described that is designed to perform indoor localization in the Smart Condo (TM). A significant aspect of the framework is that it mainly operates on the basis of binary sensors - including motion sensors and occupancy sensors - and it primarily involves geometric computations.

QoI for passive acoustic gunfire localization

2008 5th IEEE International Conference on Mobile Ad Hoc and Sensor Systems, 2008
A network of acoustic arrays can localize a shooter. Each array can determine the direction of arrival (DOA) of the muzzle blast. Some arrays can also see the shockwave generated by the bullet as it travels at supersonic speeds. These arrays can also estimate the range to the shooter as a nonlinear function of the DOA and time difference of arrival ...
