Research And Application On High Availability Real-time Processing Technology Of Missile External Measuerement Data

In this paper,the current aircraft test and test environment as the background,in view of the many practical problems in data measurement,the paper puts forward a high availability real-time data method of missile external measurement data.With the development of missile technology in our country,the new test mode is emerging,which demands higher real-time data measurement and processing ability,and many new problems come into being.These problems will affect the integrity,real-time and accuracy of missile target measurement and tracking.This article will discuss how to solve these problems by using several methods,enhance the measurement performance,and verify these methods by simulation.The work accomplished includes the following: Firstly,the whole process extrapolation technology based on ballistic feature has been developed to solve the incomplete trajectory problem caused by many factors,such as missile,measurement and control site,and measurement equipment.In this paper,the trajectory extrapolation of each flight section of missile is modeled,and the key parameter acquisition technology of extrapolation model and extrapolation model is discussed.The construction of extrapolation model can be used to generate the whole trajectory of extrapolation.Secondly,in order to optimize the data source in the measurement and control process,the real-time trajectory data precision lifting technology is studied.The optimization model is constructed by using the multi-R automatic Fusion algorithm,the pure continuous wave location speed measurement algorithm and the high precision landing point prediction algorithm.By using the least squares vector intersection method of Multi station,the problem of multi-source anomaly data is solved,and multiple R automatic Fusion and pure continuous wave positioning velocity are realized.At last,this paper studies the real time recognition technology of ballistic missile,analyzes the target characteristic of ballistic missile group,puts forward the method of determining the main target based on multivariate information and the target trajectory recognition method based on the deviation characteristic,constructs the multi-target human-machine combination recognition model,and improves the ability of multi-targets recognition.
