HU Yan-ya · Electronic Information Warfare Technology · 2013
A double Duffing oscillator difference method is described for the detection of weak signal in the basic 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 detection frequency bandwidth is increased without affecting the detection precision,and the amount of calculation is lower,the arraysis lessen,and also the errorrate.
