Study Of The Technology Of Remote Setting On Information Link Of Fuze And Weapon System

From Kuwait war, Kosovo war and Iraq war, people will get many of new apocalypse, these wars will also affect military thoughts, battle theory and weapon's development trend in future. Using landform matching guidance missile and low altitude cruise missile make it easy to breach outer defense. Once outer defense is broken, we must establish weapons automation system that responses fleetly to entreat these attacking targets effectively. Through the technique of fast information link of fire control system and ammunition fuze, the fast setting of fuze will be realized. Thus, remote setting becomes the necessary trend of short range anti-missile's development.Using high frequency wireless remote setting technique to set the electronic time fuze of rocket bomb automatically and fast, the fire control system will fast and automatically transmit the attacking target's new data (setting time) to the flying pellets in the trajectory to control the bombing dot exactly, barrage wall will appear in front of the attacking target and hold back the missile, this will improve the ability of short range anti-missile.This dissertation firstly compares modulation and demodulation modes, chooses 2FSK signal carrier modulating and non-relevant demodulation, and analyses the performance of anti-noise of 2FSK system, and expounds the circuit designing method of the remote set fuze and gives the demonstration of the relevant circuit design.Because of the reason that the setting information must be transmitted to the fuze precision in a very short time and the setting precision must be high, thus, the data coding of the fuze setting time is one of the key techniques. This dissertation expounds the particular process of the system coding design.Adopting high frequency radio wave to set fuze information on the outer trajectory, the information's anti-jamming in the setting process must be settled. The dissertation discusses the choosing of the setting area and gives the concept of the setting window, and analyzes and researches the system precision and the rate of error code. The dissertation analyzes the jam problems that remote setting fuze will meet, and puts forwards the corresponding settle means to offer theory guidance for the dependability design and realization of the system.This dissertation discusses the design means of Loop antenna and Microstrip patch antenna, and gives the particular design process of the 70mm caliber missile bomb Microstrip patch antenna. And from the experiments, the dissertation elicits the choosing principle of the project antenna and the receiving antenna.Finally, surrounding four technique characteristics of high over loading, small volume, low cost and low consumption in the fuze design, and this dissertation puts forward the necessity and importance of the realization of high over loading, small volume, low cost and low consumption in the fuze design, and puts forward concrete technique track. Combining the design of remote setting fuze, the dissertation presents the concrete means and measure to realize high over loading, small bulk, low cost and low consumption.
