US Patent:

6937186, Aug 30, 2005
Filed:

Jun 22, 2004
Appl. No.:

10/875025
Inventors:

Robert B. Dybdal - Palos Verdes Estates CA, US
Denny D. Pidhayny - Los Angeles CA, US
Assignee:

The Aerospace Corporation - El Segundo CA
International Classification:

G01S007/40
US Classification:

342173, 342 73, 342 74, 342 75, 342 80, 342147, 342149, 342165, 342174, 342175, 342195, 342359, 342360, 343703
Abstract:

A method for main beam alignment verification includes providing data pertaining to one or more patterns associated with an antenna, measuring power levels of a signal acquired by the antenna, and comparing the measured power levels with the data to determine whether a direction of the signal is incident upon a main beam of the antenna.

US Patent:

6965343, Nov 15, 2005
Filed:

Jun 17, 2004
Appl. No.:

10/872094
Inventors:

Robert B. Dybdal - Palos Verdes Estates CA, US
Denny D. Pidhayny - Los Angeles CA, US
Don J. Hinshilwood - Carson CA, US
Assignee:

The Aerospace Corporation - El Segundo CA
International Classification:

H01Q003/00
G01S005/02
US Classification:

342359, 342372, 342424
Abstract:

A method for antenna tracking includes providing a central feed element in an antenna focal region with additional feed elements in an azimuth coordinate to provide a multitude of feed elements that each have a static beam position, and varying ratios of amplitudes of adjacent feed elements of the multitude of feed elements to electronically steer a beam between the static beam positions.

US Patent:

7239275, Jul 3, 2007
Filed:

Mar 22, 2004
Appl. No.:

10/807587
Inventors:

Robert B. Dybdal - Palos Verdes Estates CA, US
Denny D. Pidhayny - Los Angeles CA, US
Assignee:

The Aerospace Corporation - El Segundo CA
International Classification:

H04B 7/10
G01S 13/00
US Classification:

342362, 342159, 4552761
Abstract:

Methods and systems for tracking signals with diverse polarization properties address both sensitivity and antenna tracking performance issues. In one embodiment, complex weightings for matching a polarization of an incident signal on a data channel are determined, and the complex weightings are applied to a tracking channel such that an antenna system polarization is matched to the polarization of the incident signal. In another embodiment, orthogonally polarized tracking channel components of an incident signal are processed to make a determination as to which of the orthogonally polarized tracking channel components is stronger, and this determination is used to select a polarization of a data channel to reduce a polarization mismatch loss.
