Linear Fm Fixed Distance Fuse Rf Circuit Design And Simulation

Fuze is playing a more and more important role in modern war. FMCW signal, with its a very low probability of intercept(LPI) characteristic and greater advantage in the range resolution then other fuze, is used widely by fuze for its inherent advantage. The theoretic analysis of triangular FMCW and the design of RF front-end of FMCW fuze form the major content of thesis.1) In the first part of thesis, introduced the basic characteristic of triangular FMCW signal and principle of FMCW signal ranging. Then analyzed the selection criteria of triangular FMCW signal's parameters, finds several ranging error reasons.2) Secondly; this paper discussed the theory of autodyne in radio fuze. According to the topological structure of oscillator that used; find out the formulas of oscillating frequency.3) Using RF design software ADS simulated the circuits of triangular FMCW fuze, Plate Making with ProtelDXP 2004; Debugging circuit and compare results with simulation results.
