IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2281-2294, November 2024.The technique of localising a moving target through multiple independent observation stations has attracted interest in a number of fields. The problem of moving source localisation is discussed based on frequency of arrival (FOA) and angle of arrival (AOA) measurements. The authors present a closed‐form solution and bias reduction method using FOA and

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 ...
