Abstract

A method of providing a polarized radio frequency scanning source is provided. The method including 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. The two or more synchronized polarized RF carrier signals with the predetermined relationship between their amplitude modulation can obtain a periodic or non-periodic scanning range, rate and frequency.

Claims

1. A method of providing a polarized radio frequency scanning 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 predetermined scanning range, pattern and frequency.

2. The method of claim 1, wherein the two or more synchronized polarized RF carrier signals with the predetermined relationship between their amplitude modulation obtain a periodic scanning range, rate and frequency.

3. The method of claim 1, wherein the two or more synchronized polarized RF carrier signals with the predetermined relationship between their amplitude modulation obtain a non-periodic scanning range, rate and frequency.
