Study on target detection technique of chaos-based modulation [radio fuze application]

In order to enhance the anti-jamming and detecting capability of a radio fuze, a means, which applies a chaotic signal to the detecting technology of a radio fuze, is presented in the paper. The system structure of a chaos modulation radio fuze is given; the characteristics of the reflected signal and the selection of the basic parameters are analyzed. Several key techniques, such as the correlative demodulation and so on, are studied. The result shows that it is feasible to apply the chaotic signal to the wave modulation of a radio fuze to enhance its anti-jamming and detecting capability.
