【摘要】 获取跟踪目标的运动速度、加速度可以预测目标后续的空间位置,对经纬仪持续捕获目标和地面武器系统攻击参数的确定具有重要的现实意义.在分析经纬仪跟踪空中目标原理的基础上,应用最小二乘曲线拟合法,建立目标在X,Y,Z方向的实时运动曲线方程,进而得到目标3个方向的速度、加速度与时间的函数关系,运用矢量运算确定了目标的瞬时速度、加速度参数.仿真了两台光电经纬仪交汇跟踪目标的跃升机动飞行,验证了上述方法的正确性.更多还原

【Abstract】 The velocity and acceleration of a target being tracked are necessary parameters to forecast its dimensional position,and important for photoelectrical theodolite capturing the target continuously as well as for the accurate attack of the earth-base weapon.Based on the principle of photoelectrical theodolite tracking target,the least square method is adopted to fit the moving equations of the target in X,Y,Z direction respectively.The functions between the target’s instantaneous velocity,acceleration and the time in X,Y,Z direction are obtained.Using vectors operation the instantaneous velocity and acceleration of the target at any time are determined.An example for mobile climbing fly of a target tracked by two intersectant photoelectrical theodolites is simulated,which indicates that the method is valid.更多还原
