Research On The Best Initiation Control Technology For Typical Projectiles

With the continuous development of aerospace technology,aerial targets appear with the features of variety,high speed and wide range,making missile-target encounter condition more complex.Therefore,more and more missiles are equipped with guidance-fuze integration technology.The maximum damage control technology in guidance-fuze integration which this paper researchs has the function of predicting the optimal detonation point of warhead and generating a signal to detonation at the exact point by combing the missile-target encounter parameters and targeting properties obtained from the guidance system,with what the fuze itself detects,which would consequently cause the maximum damage.Firstly,the paper chooses prefabricated fragment warhead as an example for analysis.By analyzing the spatial distribution,the dynamic damage area and damage capacity of the warhead fragments,we put forward one warhead maximum damage algorithm that can get the optimal detonation point,and use this algorithm to describe some influential factors of fuze-warhead coordination efficiency,which verifies the algorithm.In consideration of many fuze systems,this paper chooses the Traingle-wave FM Fuze,which is widely applied in air-to-air missiles.Based on the principle analysis of Traingle-wave FM Fuze,the paper takes missile-target encounter condition and using the CZT algorithm and the time domain under sampling algorithminto an overall consideration,simulates the fuze echo signals and handle it to measures distance and speed with MATLAB software,and briefly analyzes the actuations which some interferences generate.Finally,this paper makes an integrated simulation based on Guidance Integrated Fuze system theory.
