“The proposed IRST system will be a high-end strategic technology product in the field of defense avionics and technically competitive to existing IRST system in the global market with features of Television Day Camera, Infrared & Laser sensors in a single window for air-to-air and air-to-ground target tracking and localization,” HAL said in a release.
The Long Range Dual Band Infrared Imaging Search and Track System (IRST) for SU-30 MKI being developed by HAL & BEL will feature Focal Point Array (FPA) sensors in two bands. It will facilitate improved target recognition and better discrimination of the target from background IR radiations.
Typically, a dual-band IRST would operate in the 8-12 µm LWIR band and 3-5 µm MWIR band. Hot objects such as exhaust ports and engine plumes are more pronounced in the MWIR, while airframes, fuselages, and missile hard bodies are more pronounced in the LWIR. Water vapor absorption dominates in the LWIR, while carbon dioxide absorption dominates in the MWIR. Solar reflections are significant in the MWIR but suppressed in the LWIR.
Major advantage of the domestically produced IRST, “an indigenous IRST would accrue from the fact that its operating software would be home coded, allowing for improvements, better sensor fusion (correlation of IRST targeting data with the targeting data obtained from an AESA radar and/or another sensor) & direct integration with weapon systems. For example, it would be possible to directly feed IRST output to air-to-air missile sensors before launch!”
