The feature of magnetron exciting process can be used in the Specific Emitter Identification of self-oscillatory emitters.In this paper

a Particle In Cell (PIC) simulation was taken to verify a magnetron’s empirical circuit model and the features derived.At the beginning

the Slater circuit model was given

based on which the transient and steady solutions of the free and controlled oscillations were derived.Then the pushing coefficient feature

self-excitation exponent feature and the steady solution feature were presented.After that

a magnetron PIC simulation model was set up.Using the model

a free oscillation process was simulated to verify the pushing and exponent features.A controlled oscillation process was simulated to verify the pushing and steady solution features.The analysis results prove the effectiveness of the features.
