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.

Passive Localization Algorithm for Remote Multitarget Localization Information

IEEJ Transactions on Electrical and Electronic Engineering, 2020
The development of wireless communication has led to the wide application of passive localization. Although passive localization has strong antijamming and concealment, its accuracy will be reduced due to false location. In order to solve the above problem, particle swarm optimization–back‐propagation (PSO‐BP) algorithm was used to improve the accuracy

Passivity and localized corrosion

Anti-Corrosion Manual, 1988
Passivity and localized corrosion is discussed using iron, iron-chromium, iron-chromium-nickel alloys and aluminium as examples. A brief description is given of the prevailing ideas regarding the nature of the passive film and the processes by which its protective properties are lost when breakdown of passivity and localized corrosion occurs.

Indoor localization using passive RFID

SPIE Proceedings, 2011
Radio frequency identification (RFID) systems based on passive tags are used successfully in a wide range of object identification applications. However, the increasing needs to meet new demands on applications of localization and tracking create a new field for evolution of the RFID technology.

Passivation and Localized Corrosion

1991
A review is made of the main models proposed for the passive state, and also for the breakdown of passivity leading to localized forms of corrosion like pitting and crevice corrosion. Some particular aspects of crevice corrosion are analysed and the use of electrochemical techniques for its study is illustrated, like potential and current monitoring ...
