Abstract
A methodology has been developed at DRDC Valcartier for the calibration of infrared (IR) cameras when taking IR signature measurements of military targets. This methodology is the basis of WinISAS (Windows Infrared Signature Analysis Software) developed at DRDC Valcartier for the radiometric analysis of IR imagery and consists of a radiometric calibration of the grey levels in the image, using extended reference blackbody sources. The methodology has been developed and used mainly for the IR signature analysis of extended targets, fully resolved by the camera IR for the IR sensor. The purpose of this memorandum is to demonstrate that the same methodology and WinISAS software can be applied to the measurement of point targets, which are targets with an angular coverage smaller than the individual detector element angular coverage in an image acquired from a two-dimensional IR focal plane array camera.
