Application of AHP and D-S evidential theory in radar seeker anti-interference performance evaluation

Abstract

Comprehensive assessment of guidance radar seeker anti-interference performance has important application value in complex electromagnetic simulation environment. Radar seeker performance evaluation is a systematic work including complex electromagnetic environment simulation, test data acquisition, and evaluation algorithm application. Evaluators need to judge how the seeker performance is based on data obtained by multiple tests. This study mainly discusses the application of analytic hierarchy process and Dempster–Shafer (D-S) evidential theory, which is based on posteriori probability in the radar seeker anti-interference performance assessment. Then, the authors give the algorithm application processes and assessment results combined with experimental data. Experiment results verify that both algorithms achieve similar assessment results, which support the reasonableness of two algorithms mutually.
