A new technique of transponder jamming is proposed which is named sinusoidal full wave rectification weighted frequency modulation jamming. Generation principle of jamming signal is being presented

its features and effect of frequency shift is analyzed. Theoretical analysis shows that this jamming can produce different degrees of false targets deceptive jamming and cover jamming effects

according to flexible choice of corresponding parameters and require lower jamming powers. The simulation results justify the correctness of theoretical analysis and the feasibility of practical application.
