Filed:

Jan 26, 2006

Appl. No.:

11/339532

Inventors:

Herbert C. Stankwitz - Clifton VA, US
Stephen P. Taylor - Ann Arbor MI, US

Assignee:

Integrity Applications Incorporated - Chantilly VA

International Classification:

G01S 13/90

US Classification:

342 25R, 342 25 F

Abstract:

Systems and methods of improving synthetic aperture radar (SAR) system are disclosed. In particular, an example system includes a radar signal radiator configured to transmit radar signal pulses that have a partial bandwidth at a regular interval. The partial bandwidth is a portion of a full bandwidth that said radar signal radiator is designed to generate. The example system also includes a receiver configured to receive radar signals returned in response to said transmitted radar signal pulses, and a processor configured to extrapolate said received signals to said full bandwidth, to thereby create high resolution SAR images.

Appl. No.:

11/652370

Inventors:

Ronald Ray Fairbanks - Haymarket VA, US
Herbert Carl Stankwitz - Clifton VA, US
Stephen Paul Taylor - Ann Arbor MI, US

Assignee:

Integrity Applications Incorporated - Carlsbad CA

International Classification:

G06K 9/40
H04N 1/38

US Classification:

382263, 358463

Abstract:

In some embodiments, the present invention relates to methods or suppressing edge ringing in images. For example, in some embodiments a method of processing an image to suppress ringing and broadened edges induced by image correction processing, includes high-pass filtering a first image to obtain a second image, processing said second image including applying non-linear apodization to said second image to obtain a third image, low-pass filtering said first image to obtain a fourth image, and combining the third image and the fourth image to obtain an output image, wherein the output image is characterized by having reduced edge-response sidelobes as compared to the first images. In some embodiments, the present invention relates to devices comprising means and/or modules to suppress edge ringing in images.
