A Short Technical Note on the IR Signatures Studies and Designing Aspects of the IR Technology Devices for Defence Aircraft

Kamal Nain Chopra, Ritu Walia

The purpose of the present communication is to give a short technical Analysis of the impotant IR Signatures Studies, and the Designing Aspects of the IR Technology Devices for Defence aircraft for optimizing their performance. The Designing Aspects have been discussed on the basis of Lock-in-envelope and Radiant Flux Attenuation by Transmission through Atmosphere, by considering equations and computations for Lock-on Envelope. The paper is expected to be very useful for the Researchers and Technologists engaged in the designing and fabricating the IR based devices for modern fighter aeroplanes, and the Techniques for protecting them from detection and enemy attack.
