Availability for Non-Exclusive, Exclusive, or Partially Exclusive 
Licensing of U.S. Patent Concerning Polarization Correlation Signal 
Processing for Ladars and Radars

AGENCY: Department of the Army, DoD.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: In accordance with 37 CFR 404.6 and 404.7, announcement is 
made of the availability for licensing of the invention set forth in 
U.S. Patent No. 6,967,617 entitled ``Polarization Correlation Signal 
Processing for Ladars and Radars,'' issued on November 22, 2005. The 
United States Government, as represented by the Secretary of the Army, 
has rights in this invention.

ADDRESSES: Office of Research and Technology Applications, SDMC-RDTC-
TDL (Ms. Susan D. McRae), Bldg. 5220, Von Braun Complex, Redstone 
Arsenal, AL 35898.

FOR FURTHER INFORMATION CONTACT: Ms. Joan Gilsdorf, Patent Attorney, e-
mail: [email protected]; (256) 955-3213 or Ms. Susan D. 
McRae, Office of Research and Technology Applications, e-mail: 
[email protected]; (256) 955-1501.

SUPPLEMENTARY INFORMATION: The invention pertains to correlating a 
received waveform of a wideband electromagnetic signal with a 
predetermined waveform. A correlating polarimeter includes a first 
antenna for receiving an electromagnetic signal and a modulator 
interconnected with the first antenna for modulating the 
electromagnetic signal. A modulated electromagnetic signal results that 
contains a different polarization state for each frequency of the 
electromagnetic signal with the amplitude of each frequency component 
of the modulated electromagnetic signal being a function of the 
particular polarization state of each frequency component of the 
electromagnetic signal. The correlating polarimeter may also include a 
linear polarizer that can be configured to pass a first predetermined 
polarization of the modulated electromagnetic signal through a first 
output thereof, a first receiver for receiving and demodulating the 
electromagnetic signal from the linear polarizer and outputting a 
received waveform, and a correlator interconnected with the first 
receiver to compare the received waveform to a predetermined waveform 
and output a correlation indicator.

Army Federal Register Liaison Officer.
