  • Non-Line-of-Sight Based Radio Localization With Dual-Polarization Antenna Arrays

    • This work presents an approach for radio-based localization in non-line-of-sight (NLOS) environments by leveraging a dual-polarization antenna array. By estimating the polarization of the received signal, it is possible to estimate the angle of reflection of a NLOS signal. An estimate of the position of the transmitter concerning the receiver can be obtained based on a joint estimation of the reflection angle of several NLOS signals together with their respective directions of arrival (DOAs) and time differences of arrival (TDOAs). A set of numerical simulations is used to assess the performance of the proposed method. © VDE VERLAG GMBH. Berlin. Offenbach

  • GNSS Aided Non-Line-of-Sight Radio Localization via Dual Polarized Arrays
  • 2020
  • Ingår i: WiP Proceedings of the International Conference on Localization and GNSS (ICL-GNSS 2020). - Aachen : Rheinisch-Westfaelische Technische Hochschule Aachen.
  • Konferensbidrag (refereegranskat)abstract
    • This work presents a radio based localization approach that is capable of accurately positioning radio emitters even when no direct line-of-sight signal is available. A dual polarized array is employed along with the space alternating generalized expectation maximization (SAGE) algorithm. To lighten the computational load and improve the accuracy of the proposed method, Global Navigation Satellite Systems (GNSS) positioning is used to initialize and limit the search area of SAGE. A set of numerical simulations is presented, highlighting the performance of the proposed method. © 2020 for this paper by its authors.
