Paper Abstract

Infrared Oblique reconnaissance from an aircraft can be achieved either by use of FLIR (Forward Looking Infrared) sensors or by using IRLS (infrared line scanners) when such sensors are pointed in an oblique direction. Each sensor has certain problems associated with its use. The FLIRs offer good resolution and sensitivity but have a narrow field of view while the IRLS sensors have wide coverage but suffer from sampling overlap and underlap mismatch in each scan. These problems are discussed. Some solutions are mentioned which tend to maximize resolution and sensitivity so that oblique imaging at long slant ranges near the horizon can be accomplished on a low altitude reconnaissance mission. Current development activity at Honeywell toward these goals is briefly noted.
