摘要
以建立超短波跳频通信对抗分布式仿真系统为目的,首先给出了联邦的体系结构及跳频发信机、接收机成员的复包络仿真框图。其次,讨论了仿真系统实现的关键技术,包括帧处理结构、跳频序列发生器、路径损耗与多径信道仿真模型、信号传播延时及干扰信号的仿真等。最后,给出了仿真系统实例,分析并仿真了频率偏移对多频连续波干扰性能的影响。联邦开发实践表明,该系统具有良好的可扩充性和可重用性。
With the objective of developing distributed simulation system of frequency hopping ultrashort communication countermeasure system, the federation architecture and the complex envelop simulation block diagrams of FH transmitter and receiver are presented at first. Then critical technologies of simulation system are discussed, including frame processing structure, FH sequence generator, simulation models of path loss and multipath channel, simulation of signal propagation delay and jamming signal etc. Finally, an example of simulation system is presented, and the influence of frequency excursion on performance of multi - tone continuous wave jamming is analyzed and simulated. Practice in developing federation indicated that the simulation system has good extensibility and reusability.
