FrequencyHoppingTechnology
在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)

说明: 3) 跨平台文档结构的调整 项目文档是始终贯穿着整个系统的,但由于Windows系统与其他系统如Linux等的文档结构不同,项目的可移植性将会受到限制,因此强调可移植性的本系统中跨平台文档结构的调整是必不可少的,我们预计在这一阶段以Windows 和 Linux为基础出2套相应的代码版本,基础代码部分不变,只是在文档接口及对应的应用工具上做出相应的选择。预计所需时间为二个月,包括平台的移植,接口的研究和开发等(3) cross-platform document the restructuring of the project document is always run through the whole system, but the Windows system and other systems such as Linux and other documents of different structures, the project will be subject to the portability restrictions of the emphasis on portability cross-platform file system structure is essential, we expect at this stage in Windows and Linux based on the 2 versions of the corresponding code, the basis of some of the same code, but in the document application interface and the corresponding tools choices accordingly. Expected time required for months, including platform migration, interfaces, such as research and development)
