1. A method for determining an angular orientation of a sensor relative to a source, the method comprising:

  • amplitude modulating at least two synchronized polarized Radio Frequency (RF) carrier signals with a predetermined relationship between their amplitude modulation of their electric field components and their polarization states to provide a scanning polarized RF reference source with a desired scanning range, pattern and frequency;

    detecting the scanning polarized RF reference source at the sensor; and

    using peak detection analysis on a signal detected at the sensor to determine the angular orientation of the sensor relative to scanning polarized RF reference source.
