ES-DPR: A DOA-Based Method for Passive Localization in Indoor Environments. [PDF]

open access: yesSensors (Basel), 2019
In this paper, we propose a novel indoor passive localization approach called eigenspace-based DOA with direct-path recognition (ES-DPR), based on a DOA estimation algorithm with multiple omnidirectional antennas deployed in a uniform linear array (ULA).

Multi-Sensor Passive Localization Using Direct Position Determination with Time-Varying Delay [PDF]

open access: yesSensors, 2019
This paper focuses on passive emitter localization using moving sensors. The increase in observation time is beneficial to improve the localization accuracy, but it could cause deterioration of the relative motion between the emitter and the sensors ...

Multi-target passive positioning with signal classification and MIMO radar [PDF]

open access: yesScientific Reports
Radar-based passive localization plays an important role in non-cooperative sensing and situational awareness. In angle-of-arrival (AOA) based passive localization, dual-aircraft cooperative positioning offers advantages such as reduced model parameters,

Passive Localization Through Channel Estimation of On-the-Air LTE Signals

open access: yesIEEE Access, 2019
Wireless communication signal is a kind of coherent illuminator, and it can shed light on surrounding environments. The mobile terminal receives the signal and estimate the propagation channel, and can sense the moving objects passively. The localization

Passive Localization Algorithm for Radiation Source Based on Long Synthetic Aperture

open access: yesLeida xuebao, 2020
When the direction-of-arrival estimation is made by a single platform, the localization accuracy decreases with increases in the distance from the radiation source, which means the localization accuracy of the azimuth of the radiation source at long ...
