摘　　要：在需要对目标进行实时跟踪瞄准的火控系统设计、论证与分析中,经常要估算目标运动的角速度、角加速度及其变化规律,以作为跟踪系统设计的依据,但目前很难找到针对此类问题的系统性论述。为此,以经常涉及的空间远程目标为对象,从理论上对地平式跟踪系统中目标运动的角速度、角加速度、最大角速度、最大角加速度等物理量进行了严格推导,给出定量的计算公式,并将理论计算结果与对某目标的实测数据进行了比较,证明了理论公式的正确性。从推导过程看,所得公式同样适用于近程目标。Many fire control systems nowadays need real-time tracking and pointing to targets.In their design,demonstration and analysis,it is often necessary to estimate the angular velocity,angular acceleration and their variation law to provide basis for designing tracking and pointing system.However,systematic exposition for these issues is hard to find.Therefore,theoretical deductions are strictly made for often-involved long-range space targets to obtain quantitive formulae about angular velocity,angular acceleration as well as their maximum values.The deductions specially aim at ground-level tracking systems.Results of theoretical calculations with these formulae are compared with some real-measured data from a target.Conformity of the two types of results proves all the formulae are correct.The obtained formulae are also fit for short-range targets,which can be seen from the procedure of deduction.
