摘要

如何快速高效的生成各种雷达信号，形成可供雷达对抗侦察装备进行操作训练和性能测试的信号环境，是信号模拟领域一个急需解决的关键技术。探讨了信道化发射技术的基本原理，分析了基于多相滤波技术的数学实现模型，以脉间捷变频信号和脉组捷变频信号为例进行了仿真分析，仿真结构表明了该技术的有效性和可行性。%How to generate multi-channel signals quickly and efficient, and to construct signal environment to meet the EW force training requirement and radar reconnaissance system test is one of the key technologies in signal simulation. The essential principle of the channelized trans-mitter technology is studied, and the mathematical model based on poly-phase filter is analyzed. Take the signals of frequency agile from one pulse to another and during the different group pul-ses into account, the computer simulations are done and the validity and feasibility of using the technology to realize signal simulator is showed.
