Paper Abstract

The scanner receiver unit (SRU) is an infrared line scanner developed for the German Airforce Electronic Combat and Reconnaissance (ECR) Tornado. Its unique, variably sampled sensor array provides horizon-to-horizon coverage without bow tie distortion, normally associated with line scanners at long slant ranges, thus obviating the need for supplementary sensors. A serial input enables an external processor to calculate and provide a number of 'mapping' parameters. These effectively steer the SRU, determining where and how many samples are to be taken within the scanned field of view. This programmable field of view feature enables a standoff capability for heavily defended areas such as airfields. Now in service with the German Airforce, SRU acceptance was not without teething problems, all of which have been rectified. While the effects were not directly associated with the SRU itself, the solutions were applied to the SRU to assure compatibility within different systems; the main improvement being the incorporation of a correction signal derived from the spin mirror and coupled into the sampling clock to eliminate image break up caused by variations in spin mirror rotation due to external influences. In the infrared imaging system developed for the ECR Tornado, the SRU is coupled to a recorder using dry silver film, which provides for on board development and viewing. Honeywell is now in the final phase of developing a highly integrated Reconnaissance Management Unit for the German Airforce Reconnaissance Program, to facilitate use of digital tape recorder technology. This development will extend the SRU's capabilities and ensure its use into the next century.
