<p>A direction finding system comprises one or more receivers which are movable in use. Each receiver includes an automatic heading device (4) to detect receiver orientation theta and an automatic location device (5) to detect receiver position x, y. Receivers optionally include timing devices (6). In a method of target tracking over time, changes in receiver orientation and position are compensated for automatically to determine instantaneous target positions. <IMAGE></p> |
