Analysis On The Firing Accuracy Of Near Defense Naval Gun In Swaying Environment

With the development of science and technology,the competition between various countries in the marine field is becoming increasingly fierce.The threat of anti-ship missiles to ships is increasing day by day,and near-aircraft defense is the last resort for terminal defense.Firing accuracy is an important factor in determining the effectiveness of near-anti-guns.The impact of the special structure of near-anti-guns and the marine environment on firing accuracy is worth exploring.This article firstly introduces the overall situation of the fire control system and the coordinate transformation applied in the fire control solution process,and then introduces the linear rate fire control system and angular rate fire control system.,analyzes and derives the error model of the fire control system from different angles,and Compare the linear rate fire control system with the angular rate fire control system.This article uses statistical theory to derive and simulate the wave motion under different sea conditions.By establishing the transfer function of the ship’s rolling motion and the ship’s motion model in the waves,and according to the wave motion model obtained above,the final simulation model is about different types of ships encountering rolling,pitching motions in and heave motion in different environments.This article clarifies that the firing error of the shipboard fire control system is related to the firing accuracy,and then analyzes and discusses the firing error of the shipboard fire control system.Taking the more special shipborne weapon rapid-fire revolving gun as an example,analyzes the shipboard weapon The impact of disturbance on shooting accuracy.Finally,this article analyzes and discusses the measurement errors of slope distance,high and low angle,pitch rate and lateral angular rate,and the impact of output delay on the firing accuracy of shipborne weapons.
