Radio Fuse Experimental Interference Technology Research

As the radio fuze has been used widely, the study on method of fuze jamming and fuze anti-jamming capability evaluation becomes more important. To build a jammer base on Soft-Radio platform made the research on fuze jamming and fuze anti-jamming capability evaluation much more conveniently. The structure of this paper is as follows:(1) Introduce the principles of typical radio fuze, analyze the fuze jamming principle respectively, and then provide the basis of build jamming signal.(2) Based on the Soft-Radio System and the language- LabVIEW 7.1, design and develop the radio fuze laboratory jammer which the main functions include: signal capture, carrier frequency estimate, modulation classification, signal demodulation, modulation parameter estimate, jamming signal build.(3) Design and develop continuous Data Acquire System, which is used to supervise the fuze detecting and action output of measured radio fuze, based on multi-functions data acquisition module, and meanwhile record the experiment data.(4) Take autodyne CW-Doppler fuze and amplitude affected FM fuze as examples, analyze the experiment data of this two structure fuze, which obtained results meet the analysis theory.
