Researsh On Antiaircraft Verifying Shooting Of Closed-loop Based On XX Type Vessel Gun Fire Control System

This thesis probes into the fire control system of naval vessel gun and the theory of vessel gun antiaircraft launch,studies the antiaircraft shooting theory of xx type vessel gun fire control system and the method of using closed - loop to verify the launch to air aim . The fire control system of xx type naval vessel never has using closed- loop to check the shooting to air aim in our country,and it is open- loop . For aerial tarial targets, it only use dummy shooting, don't have other kinds of verifying launch . Because air aim is very quickly, dummy shooting may delay the fire control system's reaction time and even bungle the opportunity for combat. This verifying launch of closed loop supplyes a new check shooting method to the fire control system .A new closed-loop spotting mathematical model of medium caliber shipborne gun weapon system to air is established,it solves many kinds of problems such as window indication,projectile sequential identification,filtering method,prediction,miss parameter evaluation,method against projectile missed measure and so on.By simulation,system accuracy and hit probability is greatly improved.The model is now implemented in a shipborne gun weapon system.
