摘要
激光制导、微波制导的导引头由于不具备可视化功能, 在实际环境中进行性能考核时, 导引头是否成功截获指定目标、截获目标后的稳定跟踪过程是否正常以及在稳定跟踪过程中出现的问题都不易得到及时、准确的定位和分析。文中设计的可视化评估系统可有效解决上述问题, 通过加装可见光成像系统同步伴随导引头运动的方法, 将导引头搜索、跟踪目标的过程清晰成像, 直观显示导引头的整个工作过程, 同时利用图像跟踪系统和图像存储系统保存关键性能参数, 试验完成后对导引头的输出参数及跟踪性能进行验证及处理, 进而对导引头的性能参数进行分析和评估; 通过动态跟踪或加载干扰源试验验证, 该方法能利用可视化系统可靠同步跟随不可视导引头的运动, 并对导引头跟踪过程进行定性观察及定量分析。该方法不仅可以克服室内仿真环境不太真实的缺点, 又可进行多次重复性研究, 性价比高, 为导引头性能评估提供一种比较适用的研究手段。
Abstract
Laser and microwave guidance seekers donnot have the ability of visualization, therefore during the performance evaluation or bidding test in real environment, it is hard to get intuitive and accurate feedback and positioning for the cases whether the seeker succeeds in intercepting object or not, whether it is stable to track target regularly and some accompanying problems.The visual evaluation system designed could effectively solve the above problems.A tracking platform with simultaneous accompanying seeker was installed by a visible imaging system, which could image the seeker’s searching and tracking process clearly and visualize its entire working process;at the same time, the image tracking system and image storage system were used to save key performance parameters.After accomplishing tests, the seeker’s output parameters and tracking performance were verified and processed so as to analyze and evaluate the performance parameters of seeker.Dynamic tracking and loading interference source tests verify that, this method could synchronously follow the movement of the invisible seeker by using visual system to achieve the purpose of qualitative observation and quantitative analysis of the seeker tracking process. It could not only overcome the inaccuracy of indoor environment, but also provide a more economical and feasible research means for the performance evaluation of seeker.
