Modeling And Simulation Of The Guidance Handover Probability Calculation And Evaluation System

With the development of weapon systems and science and technology,the threat performance of targets in the airspace has been continuously improved.For air defense missiles with enhanced airspace control capabilities,their performance has become an important factor in determining the outcome of the battle.In order to improve the overall combat effectiveness of the precision guided weapon system in modern complex battlefield environments,the hybrid guidance technology is increasingly used in air defense and antimissile.However,regardless of the type of compound guidance method,the midcourse guidance to the terminal guidance segment needs to be resolved.Reliable and smooth transition and the determination of interception-that is,the problem of mid-to-last guidance transition.This paper aims at the precision analysis and development requirements of the proposed missile system,and makes a detailed theoretical analysis of the mid-to-end guidance shift.Using the missile system’s parameters and performance indicators to calculate the precision of the mid-to-end guidance shift,while assessing the error indicators of the various subsystems centered on the shift probability,complete the evaluation of the system indicators,and develop a set of software to evaluate the missile system accuracy.This paper analyzes and studies the precision of handover based on middle and end guidance,and proposes Monte Carlo method and covariance analysis to evaluate the system accuracy.At the same time,it analyzes and designs the main error sources that affect the shift.Based on the matlab environment,the software framework construction and modeling simulation are completed,and the intuitive human-computer interaction operation is designed through the design of the matlab gui interface to complete a good interface design.The missile system accuracy evaluation software based on the probability of mid-to-final guided handovers is designed to help designers quickly,accurately and reasonably analyze the overall precision design requirements of the system,grasp the important links affecting the accuracy of shifts,and formulate error indicators for each link,thus realizing the system The purpose of accuracy design is to have a margin to master together and overcome difficulties together,to achieve the best system accuracy,to avoid the risk of system closure in the development of models,shorten the development cycle,and improve equipment performance.This is of great significance to the technical design of the air defense missile system and the overall development process.
