More Information
Summary:An apparatus and method for acquiring image data from a scanned, multi-bank time-delay and integrate (TDI) focal plane array (FPA) detector. Specifically a method and apparatus for warping and combining sequentially-acquired image data of a scene portion from multiple TDI detector banks into a single image having improved image quality, thereby providing improved FPA sensitivity. Also, a method and apparatus for enabling sensitivity and areal rate trade-offs in a multi-bank, scanning TDI FPA based on the number of TDI banks being used for sequential imaging of the same scene portion.
