GPISAR - General Purpose Inverse Synthetic Aperture Radar

Array was contracted by the Department of National Defence (DND) to provide upgrades to the General Purpose Inverse Synthetic Aperture Radar (GPISAR) software tool being used at Defence Research and Development Canada-Ottawa (DRDC-Ottawa).

The GPISAR software package was used for the processing and visualization of data collected from Radar Systems to display Inverse Synthetic Aperture Radar (ISAR) images of moving targets of military interest.

Under the contract, Array performed a variety of tasks:

• Enhanced the GPISAR software.
• Introduced new algorithms to improve preprocessing efficiency and accuracy.
• Redesigned the Graphical User Interface (GUI), streamlining navigation for the user.
• Introduced an Image Quality Tool (IQT).

Array successfully completed Phase I and II of this project, enhancing the capabilities of the GPISAR tool and upgrading it with the latest MATLAB version. Shortly after, Array was awarded a contract to complete the Phase III upgrades.

Array was well equipped to perform the Phase III requirements thanks to its leading in-house SAR testbed technology and SAR development toolbox. Array's past SAR experience includes developing and delivering the SAR real-time image processing software for Britain's Royal Air Force (RAF) Nimrod, Searchwater 2000MR project and delivering a SAR product for another overseas project.
