Research On Fire Control Technology Of Air Defense Missile Weapon System

Air defense missile weapon system has many advantages such as high mobility,operation flexibility,high effectiveness-cost ratio etc,which has great effect on current war,so that many countries place a great emphasis on it.Currently,battlefield environment is complex and variable,which requires air defense system can detect targets as early as possible,process the target information in time and assist the commander to make judgments quickly and accurately,and issue combat command to launch missiles to attack targets,so that a complete fire control subsystem is needed to accomplish receiving target information,controlling launcher platform to aim at target and track it,calculating firing data of target,generating parameters of missile launching area,evaluating threat level,making fire assignment plan to assist the commander to make judgments.The paper is written by combining the actual work of the author,who undertakes a fire control subsystem design in a certain air defense missile weapon system,and deep research on fire control technologies related to the air defense system.Content of this paper involves fire control area solving technology,aided decision-making technology,target assignment technology etc.Chapter two mainly introduces target firing data calculation model,including shape and main parameters of the typical killing zone of air defense missile,head-on killing zone mathematical model,chase killing zone mathematical model,main parameters calculation models of head-on launch zone and chase launch zone;Chapter Three describes the design of target threat level evaluation model,including the factors considered in target threat level evaluation,method of target threat level.evaluation and classification of threat level;in the factors considered in the target threat-level evaluation,this paper considers three kinds of factors which are possible attacking key-point of the target,IFF and types attributes of the target,urgency level of target interception,based on the development of airborne weapons and air-raid modes,as well as the mission demand of firing command control in the air defense operation.Method of target threat-level evaluation provides a target threat-level calculation method.During the classification of threat-level,it uses a common method used in the engineering practice to classify the threat-level of targets;Chapter Four describes the design of fire assignment model,and introduces the amplification in the engineering practice,including establishment of fire assignment model,process of fire assignment plan and implement in the engineering practice.Fire assignment model mainly accomplishes calculating firing data parameters of target relative to each combat vehicle,evaluating launch availability when combat vehicle prepares to attack the target,forming fife assignment scheme,making processing on the fire assignment scheme and designating target and combat vehicle to a certain fire channel based on the fire assignment starting-line and ending-line.The chapter also introduces the amplification of method and parameters introduced in this paper during the fire control subsystem design of a certain air defense missile weapon system,the subsystem can calculate target firing data based on target parameters,evaluate target threat level of each combat vehicle with threat level evaluation method,and generate aided decision-making plan to assist the commander to make judgments,realize automatic target assignment by fire control subsystem or manual target assignment by the commander.With this subject,this paper selects detailed parameters and projects some solutions integrated with the features of combat vehicle to settle the actual problems,such as evaluation of target threat-level,fire assignment arithmetic etc,during the development of fire control subsystem.After performing software simulation and system test,technologies used in this paper are confirmed to be feasible and meaningful for engineering practice.
