摘　　要：在飞行器试验过程中,中心机需要实时向测控设备发送数字引导信息,使测控设备能够及时捕获目标并稳定跟踪。简单介绍目前外测实时数据处理中所采用的数字引导算法,通过分析影响外测设备数字引导精度的主要因素,提出一种基于轨迹融合的数据精化处理和多级组合滤波方法,可以有效地提高测控设备数字引导精度,具有较高的实际应用价值。In the process of aircraft test, the center computer needs to send digital guidance information to the TT&C equipment in real-time, so that the TT&C equipment can catch the target in time and track it stably. In this paper, the digital guidance algorithm for real time data processing of trajectory tracking is introduced, the main reasons influencing the digital guidance precision are analyzed, and the data refinement processing method based on trajectory fusion and the multi-stage combined filtering method are proposed, which can effectively improve the digital guidance accuracy for TT&C equipment and has high practical application value.
