Abstract
Wind has an important effect on the ballistic characteristics of the uncontrolled projectile. Without obtaining the wind velocity information during the projectile flight, it is difficult to estimate the impact positions of the projectile accurately. To further improve the accuracy of wind speed estimation and trajectory prediction during projectile flight, a novel rotating projectile wind speed identification method based on a multi-objective chaotic adaptive particle swarm optimization algorithm is proposed. Based on the four-degree-of-freedom (4D) kinematic model of the rotating projectile, three aerodynamic parameters coefficients are selected as reference variables, three target functions are defined using the mean-square error (MSE), and two components of the wind velocity along the ground coordinate system are used as decision variables to identify the two wind components. Numerical simulations of the wind speed identification process under variable wind conditions show that the method can effectively and accurately estimate the wind values during the flight of rotating projectiles.
