Geolocation using TDOA and FDOA Measurements - ISIF

TDOA and FDOA results can be gathered and combined in various methods to produce geolocation results. Each method has its advantages and disadvantages in different measurement scenarios. TDOA-TDOA geolocation is performed, generally, by measuring DTO values using two secondary satellites, or three total satellites. By doing this, two TDOA lines are generated, hopefully, with a crossing point. TDOA – TDOA geolocation is ideal for moving targets, since the movement of the t… WebAug 14, 2024 · Three satellites TDOA (time difference of arrival) location system is a kind of passive electronic reconnaissance location mode, which uses three formation flying satellites to determine two equal time difference surface by measuring the time arrival difference of radar emitter signal.
