IET Signal Processing, Volume 17, Issue 2, February 2023., 2023 The prior information carried by the known waveform of the reference signal to reduce the negative impact of random noise is exploited, and a coherent and an incoherent method is proposed to estimate the TDOA and FDOA parameters between two moving receivers.

IET Signal Processing, Volume 16, Issue 8, Page 1002-1010, October 2022., 2022 Abstract Multidimensional scaling (MDS) is an attractive technique for a moving source localisation from time and frequency difference of arrival (time differences of arrival (TDOA)/frequency differences of arrival (FDOA)) measurements. However, its optimality has not yet been proven theoretically because of the difficult Moore–Penrose pesudo‐inverse ...

Joint localization algorithm of TDOA and FDOA considering the position error of underwater sensors
IET Radar, Sonar &Navigation, Volume 16, Issue 9, Page 1434-1445, September 2022., 2022 Abstract The joint localization method of TDOA and FDOA is widely used because it can estimate the underwater moving source well. Usually, a two‐step weighted least squares (TSWLS) algorithm is used to estimate the source. However, the noise square term is always neglected in the TSWLS algorithm.

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