A in the basic double Duffing oscillator difference method is described for the detection of weak signal principle. Its detection performance is analyzed with simulation. It is verified that the double Duffing oscillator difference system is feasible for the detection of weak signal, and the detec- tion frequency bandwidth is increased without affecting the detection precision, and the amount of cal- culation is lower, the arrays is lessen, and also the error rate.
