弹道轨迹 meaning in Chinese

ballistic trajectory

Then , we use a simulation method to create a large number of radar measurement values , produce a quantity of random numbers using computer software and add them to the radar measurement values , we use kallman filtering method to calculate the location , velocity and trajectory coefficient of the target at the moment of the final tracking point , and use the numerical solving method of differential equation to calculate the trajectory , the location of the hostile artillery or the impact point of its own projectiles , finally , we calculate statistically the random error of the tracking system and analyze the location accuracy
然后采用模拟仿真方法获得大量的雷达测量值，由计算机软件产生大量的随机数，加入雷达测量值中，用卡尔曼滤波法计算出最后跟踪点时刻的目标位置、速度和弹道系数，再用微分方程数值解法计算出整个弹道轨迹、计算出敌方炮位的位置或己方炮弹的落点，最后统计出跟踪系统的随机误差，分析定位精度。
