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.

Single‐step geolocation for a non‐circular source in the presence of satellite orbit perturbations
IET Signal Processing, Volume 16, Issue 2, Page 170-200, April 2022., 2022 Abstract This study addresses the problem of geolocating a strictly non‐circular source on the surface of Earth by a cluster of passive satellites. The known satellite positions and velocities are subject to random errors. The authors propose a single‐step satellite geolocation algorithm that directly localises the transmitter from sensor outputs using
