Algorithm and Simulation of Airborne Fire Control Aiming Angle Correction

Modern warfare is rapidly evolving towards unmanned and intelligent trends. Currently, one of the technical difficulties in unmanned aerial vehicle (UAV) airborne fire control systems is how to accurately and quickly solve shooting data. Therefore, in this paper, we propose a method for onboard fire control calculations based on variable angle integration. First, the ballistic model equations are mathematically transformed to transform the time integration into an angular integration. In each iteration, the target is always treated as a moving state, and the relation between the hit-point distance and the trajectory inclination angle is introduced. The firing elements were modified by Newton descending method. The variable angle integral method reduces the calculation times of the ballistic differential equation and improves the accuracy of the end of the hit point under the same operation conditions. The results of the simulation experiments show that the proposed method is computationally accurate and time-efficient compared to conventional methods, providing some reference for the study of airborne fire control midpoint and firing element calculations.
