Sistema de Guerra Eletrônica para autodefesa de helicópteros de combate

The present work proposes a methodology to support in the design phase of an Electronic Warfare Self-protection System for battlefield helicopters. Hence, the main threats and alternative systems were pointed out through literature review aiming the increase of survival probability in a hostile environment. The awareness of helicopter pilots on the degree of importance of the possible configurations of a self-protection system was also evaluated. The proposed methodology is based on the Analytic Hierarchy Process (AHP) method. A hypothetical situation employing three aerial platforms was analyzed by ten rotary wings pilots as a procedures validation. The results were consistent with possible real situations according to recent conflicts. This methodology gathers quantitative values to the results analysis instead of qualitative criteria, reducing the subjectivity in decision making process for acquisition and in the development of new projects.
