  • Method and apparatus to minimize antenna backside signal response and ambiguity
    Patent number: 8013792
    Abstract: Method and apparatus for minimizing antenna backside signal response and ambiguity in low frequency applications, particularly low frequency synthetic aperture radar (SAR). Various time delay elements are selectably switched into the signal path so as to cause a null to be placed in the antenna response pattern in the direction of undesired radar returns. The means for selectably switching may be dithered so as to introduce modulation onto the undesired radar return to aid in the discrimination and removal of the undesired radar return from the SAR image during post processing.
    Type: Grant
    Filed: August 6, 2009
    Date of Patent: September 6, 2011
    Assignee: The United States of America as represented by the Secretary of the Air Force
