1. A method for main beam alignment verification, comprising:providing data pertaining to one or more patterns associated with an antenna;measuring power levels of a signal acquired by the antenna; andcomparing the measured power levels with the data to determine whether a direction of the signal is incident upon a main beam of the antenna.2. The method for main beam alignment verification of claim 1, wherein the one or more patterns include a data pattern.3. The method for main beam alignment verification of claim 1, wherein the one or more patterns include data and tracking patterns.4. The method for main beam alignment verification of claim 1, wherein the data includes main beam and sidelobe angular widths for the antenna.5. The method for main beam alignment verification of claim 1, wherein the data includes monopulse error responses for a main beam region and sidelobe regions of the antenna.6. The method for main beam alignment verification of claim 1, wherein the data is a priori.7. The method for main beam alignment verification of claim 1, wherein multiple samples of the measured power levels at a common antenna position are averaged.8. The method for main beam alignment verification of claim 1, wherein power levels measured in the azimuth coordinate are averaged.9. A method for main beam alignment verification, comprising:providing data including main beam and sidelobe angular widths for an antenna;measuring power levels of a signal acquired by the antenna at multiple antenna positions; andcomparing the measured power levels with the data to determine whether a direction of the signal is incident upon a main beam of the antenna.10. The method for main beam alignment verification of claim 9, wherein the data is a priori.11. The method for main beam alignment verification of claim 9, wherein multiple samples of the measured power levels at a common antenna position are averaged.12. The method for main beam alignment verification of claim 9, wherein power levels measured in the azimuth coordinate are averaged.13. The method for main beam alignment verification of claim 9, further including using the data to reposition the antenna.14. The method for main beam alignment verification of claim 9, further including using the data to reposition the antenna after a determination has been made that the signal is not incident upon the main beam.15. The method for main beam alignment verification of claim 9, further including using the data to reposition the antenna to align the signal with a sidelobe of the antenna.16. A method for main beam alignment verification, comprising:providing data including monopulse error responses for a main beam region and sidelobe regions of an antenna;measuring power levels of a signal acquired by the antenna at multiple antenna positions; andcomparing the measured power levels with the data to determine whether a direction of the signal is incident upon a main beam of the antenna.17. The method for main beam alignment verification of claim 16, wherein the monopulse error responses are determined from data and tracking patterns of the antenna.18. The method for main beam alignment verification of claim 16, wherein the data is a priori.19. The method for main beam alignment verification of claim 16, further including using the data to reposition the antenna.20. The method for main beam alignment verification of claim 16, further including using the data to reposition the antenna after a determination has been made that the signal is not incident upon the main beam.21. The method for main beam alignment verification of claim 16, further including using the data to reposition the antenna to align the signal with a sidelobe of the antenna.
