The US Army seeks a partner to license and commercialize a new ultra-wideband imaging system for the detection of small targets
Synthetic aperture radar (SAR) systems have been used in many applications to detect concealed targets. One of the challenges for using a SAR system in this type of application is they currently suffer various noise sources that prevent the generation of very high contrast images. As a result, small targets are often obscured or even embedded in the noise level of the image background.
Moreover, SAR images of large targets may incorrectly show a secondary side image (sidelobe) that can be mistaken as a target of interest. Currently, there exists a need for an improved signal processing technique which reduces unwanted noise and enhances image reproduction.
The Army Research Lab has developed several patented techniques to minimize the effects of internal system noise and external interference in order to provide enhanced radar images. The key innovative concept is to use randomly reduced apertures combined with image pixel classification to generate virtually noise free SAR images. This technology can be applied to methods and systems for processing images from signals as radar, x-ray CAT scans, MRI (magnetic resonance imaging) equipment, or other image generating machines.
- High contrast imaging: Significant reduction in noise level allows detection of difficult targets.
- Improved performance: False alarm rate reduction greatly enhances system performance capability.
- Adaptable: Can be used with existing radar systems.
- Collection of at least six patents that cover SAR image enhancement are available for licensing
- Potential for collaboration with world class group of Army scientists
