- W4385334792 abstract "Aimed at the problem that the track data of the air target obtained due to the vacancy and wild value do not meet the requirements of the aircraft's maneuver flight performance and there was an included angle in the track before and after the inflection point. Thus, we propose a trajectory smoothing algorithm based on the improved cubic B-spline curve of genetic algorithm to improve the quality and accuracy of the trajectory data. The first and foremost, design of a new genetic algorithm fitness function based on constraints of aircraft dynamics; there was one more point, adaptively adjust the node vector of cubic B-spline curve; the last but not the least, the smooth track was obtained under the condition of optimal node vector. The experimental results demonstrate that compared with the traditional cubic B-spline curve, the target track quality of the smoothed cubic B-spline curve improved by GA is better. The algorithm not only preserves the track details, but also improves the data quality, and can comply with the requirements of aircraft maneuverability." @default.
