Design Of Radio Fuze And Analysis Of Low Frequency Information Processing Based On Mcu

With the development of modern military technology,new requirements have been put forward for the strike effect of weapons,that is,ammunition should be set off in an appropriate position by judging the environmental information on the basis of collecting the surrounding environment information,in order to maximize the damage.This makes the acquisition and test technology of fuze become more and more important in the development of weapon system.At present,the existing fuze system based on the traditional circuit has the following shortcomings: the ability of collecting information is limited,the ability of processing environmental information is effective,takes up a lot of space and the ability of anti-jamming is poor in the complex electromagnetic environment.In view of these problems,this paper presents a design method of Radio Fuze based on single-chip microcomputer.In this paper,a radio Dopler signal test system based on C8051F330 is proposed,which is combined with the related design literature.This paper mainly completes the circuit hardware design and the corresponding software design of the test system.The hardware circuit design should first meet the minimum system of single chip microcomputer.On the basis of the minimum system,an external circuit is added to regulate the received Dopler signal and then divide it into two circuits,another way to capture the envelope of Dopler's signal.In the software design,the analog signal input by the hardware circuit is calculated and processed,which consists of several parts: the frequency program of measuring low frequency signal with the method of measuring the cycle,the ADC analog-to-digital conversion program and the data processing program.Finally,under the simulation condition,the software and hardware are combined tocomplete the data acquisition of Dopler signal and the verification of the correctness of the subsequent data processing process.After the whole verification test is completed,the related data are analyzed to determine whether it achieves the intended effect.
