An identification method for radar emitter based on variable precision rough set model(VPRSM) and gray theory
is proposed, which gets the weights of feature parameters in radar emitter by the VPRSM and then completes identification
combing with the gray theory. The radar identification is taken as an example, and related simulation results are given.
Simulation results show that the proposed method can reach identification rate higher than 90% when the SNR is −15 dB.
