摘要
空气带状线具有损耗小,功率容量高,工作频率带宽较宽等优点,广泛应用于雷达系统中。文中介绍了空气带状线行馈线在雷达系统中的工作原理及传统方法的设计难点,叙述了基于计算机辅助设计的协同仿真技术的基本思路及利用软件实现的操作方法,给出了详细的设计过程、仿真数据和测试结果。结果证明该协同仿真技术,能够较好地控制馈电网络幅相精度。
Strip line with air filled is featured with low loss, high power capacitance and wide frequency band. It has been applied in radar system widely. In this paper, the working principle and traditional design challenges of feed line in radar system are intro- duced. At the same time, the basic conception and realization method of co-simulation based on computer aided design are described. The important information including the design process, simulation data and measurement results are discussed in detail. The experimental results of the feed line show that the amplitude and phase precision arc well controlled.
