Title: Targeting Performance of SWIR/MWIR Superband Camera Systems
Abstract
Improved targeting systems allow objects to be discriminated at longer ranges due to increases in sensitivity and resolution. Recent developments in infrared camera technology have enabled detectors that span the reflective and emissive infrared wavebands. These broadband reflective and emissive systems, or superband systems, combine the shortwave infrared (SWIR), extended short-wave infrared (eSWIR), and mid-wave infrared (MWIR) into a single camera. This dissertation presents a discussion on the targeting (long range object discrimination) benefits superband systems provide compared to traditional individual infrared band systems. A comparison on the radiometric signal levels available to a superband system and the amount of complementary information in that signal compared to its constituent bands is provided. Additionally, a study on the resolution and sensitivity benefits of superband systems is presented. The dissertation concludes with a discussion on ideal system design to maximize the potential targeting benefits of superband systems.
