Infrared Suppression and Countermeasures Methodology for Advanced Strategic Aircraft

The methodology for establishing optimum infrared suppression and countermeasures requirements for a strategic or tactical aircraft penetrating an infrared threat environment is developed. The methodology recognizes that the critical factor for successful countermeasures is management of spectral energy effectively at the IR seeker rather than at the source. The effects of total air vehicle radiation, atmospheric phenomena, and IR missile seeker performance on IR countermeasures requirements are considered. An equation is developed for calculating IR jammer output power at the source.
