The role of SWIR building blocks in Hostile Fire Indication and Missile Warning Systems

摘要

Infrared Search and Track (IRST), Missile Warning Systems (MWS) and other optical target detection systems have established solutions in the MWIR, UV and LWIR bands. Imaging technology in the SWIR optical band which has small Size, Weight and Power (SWAP) has been recently added as detection means. We bring an update on recent field trials and demonstrations of Optigo's gun shot detection modules. We then provide some more insight into the advantages of using the SWIR band, and specifically InGaAs detectors for the typical HFI missions. We conclude by demonstrating that detection systems operating in the SWIR band can significantly improve their performance when the cutoff wavelength approaches longer edge of SWIR.
