基于STK的滑翔增程弹弹道可视化仿真

Visual Simulation of Trajectory of Gliding Extended Range Projectile Base on STK

为了验证弹道数据的可靠性、准确性,提高弹道仿真的真实性、可视性,利用STK软件的三维建模、三维空间计算、三维动画生成能力,将从MATLAB/Simulink得到的弹道数据转化为三维动画场景,真实的模拟了弹丸的整个飞行过程。研究人员能够控制整个仿真过程,观察到弹丸任一时刻的位置、速度、姿态及整个弹道曲线,并对比在不同条件下弹道的准确度,从而对弹道参数做出修正。弹道可视化仿真实际就是一个虚拟靶场,可以应用于滑翔增程弹的研制、生产、演示过程中。

For verifying the reliability and accuracy of the trajectory data, enhance trajectory simulation facticity and visualization, make use of the STK＇ s ability of 3 D modeling, 3 D space calculation and 3 D animation, convert trajectory data which have got from the MATLAB/Simulink into the 3D animation scenario and simulated the whole flight process of the projectile. The researchers can control whole simulation process and real - time observed to the projectile position, speed, attitude and the ballistic curve, make corrections of the ballistic parameter through contrast accuracy of trajectory under the different condition, The trajectory visual simulation can be used as virtual shooting range, be applied in gliding extended range projectile＇ s process of developed, production and demo.
