摘　　要：对网络通信中的TCP单播、广播和IP多播技术进行对比分析,针对雷达终端内部数据交换实时性要求高等特点,指出IP多播技术对比TCP单播与广播技术的优点,并对IP多播技术在VC环境下的各种实现方法进行了简要介绍,最后通过实践证明IP多播技术具备实时性高,带宽利用率高及网络拓展灵活等特点,能有效满足雷达终端实时信息交互的需要。Based on the need of radar real-time network data processing, the technologies of TCP single-east, broadcast and IP multicast are analyzed in this paper. Comparing with TCP single-cast and broadcast technology, the advantage of IP muhicast technology in radar network data processing is verified and the implementation of IP multicast by VC＋＋ is introduced. In the end, The practice identify that the IP multicast technology are fast real-time data processing, high band-using and flexible net-continuations. It can satisfy the need of radar real-time data processing.
