High-fried Fuze Design

As modern warfare requestes the high range of radio fuses, this paper demonstrates the feasibility of the high-bombing-range fuses, gives the high-bombing-range fuses block diagram of the system and some test results, describes its working principles of this high-bombing-range fuses, and analyses the reasones whice may cause ranging error, and so on.First, this paper introduces the basic knowledges of fuses, including the origines of fuses, the developmentes of fuses, the classificationes of fuses, the compositiones of fuses and the processes of reaction, the purposes and and significances of this paper, as well as the main contentes.Then, as the theoretical basis of this study, this paper introduces a basic knowledge of the radar, including the main tactical parameters and technical parameters and the relationship between them, gives a briefing classification of Mono-Pulse rada.Third, in light of the environmentes of the high-fried fuses, the paper demonstrates the feasibility of the high-bombing-range fuses, gives the high-bomeing-range fuse block diagram of the system,the realization and some test results, distributes the system parameters of the high-bombing-range fuses, describes its working principles of this high-bombing-range fuses, and analyses the reasones whice may cause ranging error, and so on.Finally, in order to improve the accuracy of the fuse, the paper researches PLL. PLL includes four parts: phase detector, SCM, loop filter, VCO, and they are separately introduced, and gives the simulation results,the realization of some circuites and test results.
