中文摘要:

      随着远程打击武器突防能力的不断提高，其在对特定目标的打击过程中形成的群目标环境越来越复杂。为了能够及早发现关键目标，达到快速发现拦截摧毁的目的，导弹预警系统对雷达太空态势感知能力的要求越来越高。基于此，针对远程打击武器飞行过程中的特点，结合雷达基本原理，对影响雷达分辨能力的关键参数进行了简要分析，提出了基于背景熵的群目标判断方法，分析了基于OS-CFAR的密集群目标检测原理方法，讨论了大小目标近距离情况下基于Clean算法的遮蔽目标检测技术。

英文摘要:

      In the test of the working performance of the flap and slat power drive unit,the measurement and control system needs to simultaneously implement multiple functions,such as load simulation,communication control,power monitoring,experimental curve drawing,experimental data storage and so on.Aiming at the measurement and control system with the requirements of multitask,high real-time performance,and large data volume,based on the LabWindows/CVI environment,tasks are allocated to different threads by using multi-thread technology.The user interface runs in the main thread to respond to user operations.The tasks of simulation load setting,communication control and experimental curve drawing are executed in the asynchronous timer,and power monitoring task is executed in the thread pool.It is verified that the application of multithreading technology can ensure that the measurement and control system can display experimental state in real time,reliably communicate with the testing device,provide stable load,and effectively control the experimental process,which meets the design requirements of the system.
