The study on the optimal filtering length for closed-loop spotting of close-in anti-missile naval gun weapon system

The close-in anti-missile naval gun weapon system adopts closed-loop spotting to improve accuracy of firing. The study analyzes the process of closed-loop spotting, pointes out the importance of calculating the optimal miss parameter filtering length to get the maximum hit projectile in all route, comes up with the miss parameter model, establishes the model of calculating calibration corrections, simulates the amount of hit projectile in all route when fighting against subsonic and supersonic anti-ship missile, figures out the regularity between the optimal filtering length and target speed and firing error corresponded by the most hit projectile in all route, and puts forward the method of using simulating result.
