Comparative performance analysis of the MWIR and LWIR focal plane array starring imaging infrared systems

摘要

This paper review the fundamental physics of IR radiation and describes the predictive techniques and the methods of signature management for the specific exploitation of Imaging Infrared Surveillance Systems for shore based or ship borne surface to surface and low altitude air to surface scenarios, which are the most widely used. The parameters affecting the performance of the FLIR systems, such as target and background characteristics, atmospheric transmission and detector features are individually analyzed, in order to reach to FLIR performance assessment using either MWIR or LWIR bands. For this purpose the special scenario of maritime applications has been paying special consideration.
