Estimating the term…
Techniques are provided for geolocation and tracking of a target emitter. A methodology implementing the techniques according to an embodiment includes receiving measurement data associated with a signal from an emitter, and receiving an estimated uncertainty associated with the measurement data. The measurement data may be provided, for example, by a radar receiver. The method further includes employing a Kalman filter to calculate a geolocation of the emitter, based on the measurement data and the estimated uncertainty. The calculation includes constraining the geolocation of the emitter to the surface of the Earth, for example in a geodetic coordinate system. The measurement data may include azimuth angle of arrival of the signal and depression angle of arrival of the signal or a time difference of arrival of the signal between two measurement platforms. The methodology may be carried out, for instance, onboard an aircraft, projectile, or missile.
