ABSTRACT:
A measurement system and an associated method for determining the positions of multiple antennas to centimeter level accuracy. A plurality of first filters, one filter for each antenna of a plurality of antennas, are each operable to obtain information from a respective one of the plurality of antennas at a primary frequency. A second filter connects with at least one of the plurality of antennas. A processor calibrates biases for the information at the primary frequency with a RF path bias calibration algorithm as a function of an output of the second filter.
