On optimality of multidimensional scaling for time differences of arrival/frequency differences of arrival based moving source localisation

open access: yesIET 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 ...

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.

TDOA/FDOA estimation method based on dechirp

open access: yesIET Signal Processing, 2016
A method based on dechirp is proposed to estimate the time difference of arrival and frequency difference of arrival between two linear frequency modulated signals. By dechirping two signals with different angles and computing the projection of cross ambiguity function (CAF) of the two dechirped signals on Doppler axis, a set of equations can be set up
