[Abstract]:This paper introduces the development of a central control system for a phased array radar. The central control system is composed of single board computer and embedded software. The main task is to manage and schedule the resources of phased array radar in order to realize its tactical function requirements. As a central control system, the most important work is to manage the mode of work. Different modes of operation correspond to different scanning airspace, and the scanning time is different. Therefore, accurate calculation and quasi-allocation of parameters are needed in order to achieve a reasonable time. Space, energy resource allocation. In addition, it must control and manage the signal processing system, and communicate with other subsystems, such as front-end system, data processing system, etc., to realize the transmission of control instructions and the data exchange of target detection results. In addition, It also controls the working time sequence of the signal processing system, realizes the functions of target extraction, data communication, system timing, fault detection and so on. In addition, in order to realize the function of the system, it is necessary to have real-time performance, so the system chooses the appropriate hardware and operating system. The specific development process is as follows: firstly, according to the general requirements of the radar system, the function of the central control system is decomposed. The main functions include operation mode management, system timing, beam arrangement, beam stabilization, front tilt angle, communication interface and other main functions. Then for different functions, the method and principle of solution are given. Then, the problem of beam stabilization is studied. Because the airborne is a moving platform with strong maneuverability and special antenna form, how to stabilize the beam is discussed in order to track the target stably, and the solution is given. In engineering practice, real-time calculation of spatial position will be carried out, and the calculated results will be sent to the corresponding sub-system. Secondly, a suitable hardware platform and operating system are selected for the above work. In order to meet the strong operation ability and throughput ability, a single board computer based on MPC7457 is selected to meet the real-time requirements of the central control system. The operating system adopts Fenghe company's VxWorks system. Then the characteristics of VxWorks operating system and the use of Tornado integrated development tools are briefly introduced. Finally, the development process of the central control software is introduced in detail, the main functions are divided, the structure of the program is analyzed, the task division and task management are emphatically introduced, and the priority of different tasks is given. This paper also introduces how to set the interrupt and carry on the connection of interrupt service program, so as to realize the management task of radar system through the combination of task, communication and timing.
