Direct position determination of moving targets based on DOA
Electronics Letters, Volume 60, Issue 15, August 2024.This letter proposes a new DPD method for moving target based on DOA. First, using a proposed cost function, the position information is obtained from the received array signals directly, which enhances the accuracy of localization. Second, utilizing the method of successional difference the velocity is extracted, which avoid the multi‐dimensional grid

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 ...

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

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 ...
