摘要: A system and method for determining location information based on a reference profile for a reference device, and a system and method for determining the reference profile. The system may determine the reference locator with respect to the reference device based on a plurality of samples obtained with respect to communications between the reference device and an object device. An adapter locator may be determined for the reference locator for samples obtained with respect to communications between a test device and object.

摘要: A system and method are provided for obtaining calibration data for a portable device relative to an object in order to facilitate defining a locator for determining a location of the portable device relative to the object. The system and method may obtain calibration data pertaining to a signal characteristic of communications transmitted from the portable device and corresponding to a known location of the portable device (e.g., truth data).

摘要: Methods and systems are disclosed and include receiving a signal via a first communication channel at a plurality of azimuth angles. The method includes determining a plurality of first communication channel phase angle differences between a pair of antennas. The method includes receiving a second signal via a second communication channel and at the plurality of azimuth angles. The method includes determining a plurality of second communication channel phase angle differences between the pair of antennas that each correspond to one of the plurality of azimuth angles. The method includes generating a first reference curve based on the plurality of first communication channel phase angle differences. The method includes generating a second reference curve based on the plurality of second communication channel phase angle differences. The method also includes generating a calibration curve that is based on an interpolation of the first reference curve and the second reference curve.
