TDLoc: Passive Localization for MIMO-OFDM System via Tensor Decomposition

IEEE Internet of Things Journal, 2023
Passive localization is an important aspect of integrated sensing and communication (ISAC). However, it is challenging to estimate the target position and velocity accurately from the receiving signals due to complex multipath propagation.

Frequency-Diversity-Based Underwater Acoustic Passive Localization

IEEE Internet of Things Journal, 2022
This article considers underwater acoustic passive localization of a noncooperative broadband source in the presence of multipath propagation. A differential transmission-loss model-based passive localization method is proposed, in which 3-D localization

A CLEAN-Based Synthetic Aperture Passive Localization Algorithm for Multiple Signal Sources

IEEE Journal on Miniaturization for Air and Space Systems, 2022
In passive localization, the received signal may come from multiple signal sources with different modulations. The modulations are usually resolved by high-order spectrum (HOS) processing.
