摘　　要：提出了一种数字图像注入式红外捕获跟踪设备跟踪性能的闭环仿真测试方法。建立了评价注入式仿真试验和实际工作2种状态下设备伺服控制回路性能一致性的指标体系,给出了一致性评估方法,分别采用理论分析、光电活动靶标跟踪和实际飞行试验得到了2种状态下跟踪性能一致性/逼真度。结果表明:目标捕获和跟踪阶段的逼真度分别为90%和96%;在同一输入目标条件下,理论分析、注入式仿真试验和跟踪光电活动靶标时的跟踪误差最大值分别为3.21',3.54'和3.12',实际飞行试验与注入式仿真试验的脱靶量均方根分别为5.7″和5.27″,说明2种状态下设备跟踪性能一致性较好,为红外捕获跟踪设备快速形成数字图像注入式闭环试验鉴定能力打下了坚实基础。A new method of using digital image injection to simulate and test the closed-loop performance of IR capturing and tracking device was proposed. Based on this,it was necessary to conclude the consistency evaluation index and the method of capability for the tracking servo loop under the injection simulation and actual conditions to improve the precision and reliability of the simulation test result. The consistencies or fidelities for tracking performance of the two conditions were obtained by respectively adopting the simulation test,photoelectric target test combined with the actual flight test method. The result shows that under the same input the fidelities of capturing and tracking phase are 90% and 96%; the maximum tracking errors of the theoretical analysis,the injection simulation test and the photoelectric target test are 3. 21＇,3. 54＇ and 3. 12＇; the miss distance RMS of actual flight test and injection simulation test are 5. 7″ and 5. 27″ respectively,which verify consistency of tracking performance under the above two conditions and provide a foundation on forming the capability of the digital image injection simulation test for the IR capturing and tracking device.
