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.
