Method for localization of mobile unit i.e. military aircraft, involves defining temporal window, and estimating position of mobile unit at given moment according to set of readings obtained for specific period

摘要

The method involves emitting a set of radio waves at a frequency that is adapted to be detected by goniometers. The mobile unit i.e. military aircraft is allowed to move along a trajectory (TRAJ). A temporal window (T) is defined during which the trajectory of the mobile unit is approximated by a segment (SEG) traversed at a constant speed, where each goniometer provides a set of readings in the temporal window. A position (p-t) of the mobile unit is estimated at a given moment according to the set of readings obtained for a specific period.
