A deep learning algorithm for joint direct tracking and classification of manoeuvring sources

open access: yesIET Radar, Sonar &Navigation, Volume 16, Issue 7, Page 1198-1211, July 2022., 2022
Abstract The remarkable success of deep learning technologies has provided new ideas for solving complex tracking problems. It is difficult for traditional algorithms to directly estimate the trajectory vector and target class from the received signal due to the limitation of modelling ability, which causes inevitable information loss.

Geolocation a known‐altitude moving source by TDOA and FDOA measurements

open access: yesElectronics Letters, Volume 58, Issue 13, Page 514-516, June 2022., 2022
Abstract Source altitude information, if known or can be measured by an altimeter, can greatly improve localisation performance. In this letter, a novel algebraic solution for known‐altitude moving source geolocation using time difference of arrival and frequency difference of arrival measurements is developed.
