A digital ASIC for synthesizing false target radar images

Modern, wideband, inverse synthetic aperture radar (ISAR) is capable of generating images of targets, rendering traditional false target decoy methods obsolete. The paper describes an application specific integrated circuit (ASIC) capable of generating false target decoy images for countering imaging ISARs. The application and operation of the ASIC in an electronic attack system is also discussed. The fully programmable chip is capable of generating images of both small and large targets, even up to the size of an aircraft carrier. This is the first reported use of all digital technology to generate false target radar images of large targets.
