With the continuous upgrading of interference technology and anti-jamming technology, how to evaluate the anti-jamming capability of anti-ship missiles comprehensively, accurately and scientifically, so as to optimize the anti-jamming technology and implement precise strikes, has become the focus of research by relevant institutions. The performance of the anti-jamming system of the anti-ship missile seeker from the perspective of contribution rate is analyzed. The five concepts of control, contribution, tolerance, universality and experience are put forward combined with the engineering application reality. The contribution rate analysis model is built through the definition and analysis of these five concepts. In addition, the analytical model has been further visualized for presentation.
