Infrared Imaging Gif Fuse Detonation Control Algorithm Research

The Guidance Integrated Fuzing(GIF)technology was investigated based on imaging infrared guidance missile in this dissertation. The core problem of imaging infrared GIF technology is realize burst control through utilizing the measurement information of seeker during ultra-short distance tracking.In the research of burst control technology based on infrared imaging seeker information utility, the precision of burst control is not satisfactory because of the very large blind area of seeker, the acquisition of measurement information is an important factor for improve the precision of GIF fuze burst control algorithm. A general GIF fuze burst control algorithm was derived on the base of ultra-short distance partial image tracking, the curve fitting and passive ranging methods were used to improve the precision and stability of GIF algorithm. The main research contents of the dissertation are described as follows:1)A general GIF fuze burst control algorithm was derived, the acquisition approach of measurement information of seeker were discussed based on algorithm realization.2) The realization of ultra-short distance tracking method was briefly discussed based on partial image tracking and the relation between tracking ability and blind area of imaging infrared seeker was quantitative analysis.3)The method of polynomial fitting for measurement information and the discrimination of burst control parameters validity were proposed, the precision and stability were better than KALMAN and a-β-y filtering algorithms.4) The passive ranging method of imaging infrared seeker based on the dimension features of target was proposed, the method can improve the presicion of burst control.5)The simulation software for imaging infrared GIF algorithm was developed, and the simulation results about burst delay/miss azimuth error estimation during various encounter conditions were proposed.
