A fast direct locator for radiation source based on composite convolution neural network
Electronics Letters, Volume 60, Issue 14, July 2024.In this article, we propose a fast source localization algorithm based on composite convolutional neural network. Our network is less complex than direct positioning scheme, but can achieve better positioning performance. It can also be easily extended to the field of multi‐source localization, which also has good robustness to small‐scale fading of ...

TDOA and FDOA based source localisation via importance sampling
IET Signal Processing, 2018 Source localisation withtime‐difference‐of‐arrival (TDOA) and frequency‐difference‐of‐arrival (FDOA)measurements is of great interest since it can provide the location information with highaccuracy.Although the maximumlikelihood (ML) estimator exhibits excellent asymptotic properties, the non‐linearity and non‐convexity of ML estimator requiremuch ...

Direction‐of‐Arrival Estimation of Electromagnetic Pulse Based on Energy Distribution
International Journal of Antennas and Propagation, Volume 2024, Issue 1, 2024.This paper investigates the direction‐of‐arrival (DOA) estimation of electromagnetic pulse (EMP) sources in modern radar system and proposes a novel EMP DOA estimation method. The method is based on energy distribution and improves the low accuracy and high computational complexity of the conventional estimation method. According to the characteristics

Distributed localization of a RF target in NLOS environments
, 2014 We propose a novel distributed expectation maximization (EM) method for non-cooperative RF device localization using a wireless sensor network. We consider the scenario where few or no sensors receive line-of-sight signals from the target. In the case of

Emitter Geolocation Based on TDOA/FDOA Measurements and Its Analysis
The Journal of Korean Institute of Communications and Information Sciences, 2013 The emitter geolocation method using the time difference of arrival (TDOA) and the frequency difference of arrival (FDOA) has more accurate performance comparing to the single TDOA or FDOA based method. The estimation performance varies with the sensor paring strategies, the deployment and velocities of the sensors.
