Abstract

With large focal plane arrays now widely available, IR detectors have entered their third generation. Performances have increased dramatically with respect to second-generation, line array detectors, due to the longer integration times afforded. For surveillance systems such as InfraRed Search and Track (IRST), however, operational requirements generally impose a very large field of regard in relation to the instantaneous field of view. This characteristic which has traditionally been obtained through scanning motion for second generation line array detectors must now be rethought to obtain staring operation for 3rd generation FPA, lest motion blurring be incurred. This paper presents several approaches considered for naval surveillance systems at Sagem Defense Securite to tackle this challenge. Three techniques are presented and then compared: fully staring systems, step-and-stare systems, and finally a "modified" step-and-stare system.
