介绍了ＡＴＭ交换技术在雷达组网通信中的应用。通过对基于中央处理站的雷达组网通信技术需求的分析，提出了一种类似于用户—服务器模式的ＡＴＭ交换结构。ＡＴＭ技术是Ｂ—ＩＳＤＮ的基础，ＡＴＭ交换技术是ＡＴＭ技术的核心，它不仅可用于民用通信业务，而且对于电子干扰环境下雷达网对密集多目标跟踪时所涉及的通信业务也很有效。文章对ＡＴＭ交换机在雷达网中的数据交换作了分析，并以计算机仿真手段评估了三种特定通信环境下输出缓冲型ＡＴＭ交换机的利用率和输出队列概率分布情况。

This paper introduces the application of ATM switching technique in the communication of a netted-radar system. By analyzing the requirements for communication of the netted-radar system based on central processing station, it presents an ATM switch architecture similar to the client-server model. The ATM is considered to be the base of the broadband integrated services digital network (B-ISDN), while ATM switching technique is the key content of ATM. It is shown in the paper that ATM switches are not only useful for the civil communication traffic but also valid for the traffic involved in the tracking of tight multiple targets in a netted-radar system under the condition of jamming. The paper analyzes the data switching of ATM switch in the netted radar system. The utilization and probability mass functions of output queue lengths of the output buffered ATM switch are evaluated in three particular communication surroundings with the help of computer simulation.
