Abstract:

An intuitive systemic model based on the systemic Yoyos and stochastic differential geometry is provided for finding a meaningful geometric description of radar specific emitter identification (SEI) . The paper points out that there is a lower dimensional state manifold, which generates signals with intrinsic signatures in every emitter, and the geometric significances of the manifold go far towards solving SEI. According to this model, the intrinsic parameters of signals can be used to explain and find effective fingerprints features of a specific emitters. Experiments on actual intercepted radar signals with the same type verify the correctness and validity of the proposed model.
