ADAPTIVE ANCHOR SELECTION AND TARGET POSITION ESTIMATION

In an example method of target position estimation, the method includes calculating initial estimated positions of a target transmitter. Each of the initial estimated positions is based on an angle of arrival estimate received from a locator. The method includes generating an error projection associ...

Beschreibung
Zusammenfassung:	In an example method of target position estimation, the method includes calculating initial estimated positions of a target transmitter. Each of the initial estimated positions is based on an angle of arrival estimate received from a locator. The method includes generating an error projection associated with each of the initial estimated positions. The error projection is based on azimuth and elevation error characteristics of the locator associated with the initial estimated position. The method includes creating a select group of the locators based on overlaps of the error projections, wherein the select group of locators comprises a subset of the locators. The method includes calculating a refined estimate of the position of the target transmitter based on the initial estimated positions associated with the select group of locators.
