FEATURE IN ANTENNA PATTERN FOR POINTING AND ORIENTATION DETERMINATION
First Claim
1. An apparatus for determining antenna pointing, comprising:
- a transmit antenna system for transmitting a signal having an adjustable boresight and exhibiting a far-field pattern including a feature in a polarization component of the far-field pattern disposed at a fixed position off a beam peak of the far-field pattern; and
a receive antenna system for scanning across the far-field pattern in the polarization component to locate the feature and determine a pointing error of the adjustable boresight therefrom.

Abstract
Systems and methods for antenna pointing are disclosed. A transmit antenna system having an adjustable boresight transmits a signal exhibiting a far-field pattern including a feature (e.g. a V-Notch) in a polarization of the signal disposed at a fixed position off a beam peak of the far-field pattern of the signal. A receive antenna system scans across the far-field pattern of the signal in the polarization to locate the feature and determine a pointing error of the adjustable boresight therefrom. The system may be applied to a cross-polarization of the signal where a co-polarization of the signal is simultaneously used for telecommunication.
