A radar fuze system based on chaotic random pulse modulation (RPPM) and random two phase modulation (RBCPM) modulation is proposed. The mathematical model of the fuze waveform, the average ambiguity function and the realization of the fuze block diagram and working principle are introduced. The generation method of the mixed modulation signal based on the chaos circuit is studied. This fuze waveform not only has the characteristics of simple structure and easy processing, but also has good ranging and speed measurement performance, as well as very low interception probability and strong anti-interference characteristics
