【摘要】：全球定位系统(GPS)基带信号可以用于导航定位设备的研发、性能测试以及生成式欺骗干扰信号的产生。针对一种基于现场可编程门阵列(FPGA)的GPS基带信号产生与控制模块进行研究,主要通过硬件电路设计和软件代码编写,利用FPGA生成C/A码、P码,利用直接数字式频率合成器(DDS)产生L1、L2载波等功能,实现了多路可控增益GPS信号同时输出。测试结果表明,本设计输出增益可调、输出频点可控,可以为射频模块提供多路基带信号及控制信号。
[Abstract]:Global Positioning system (GPS) baseband signal can be used in the research and development of navigation and positioning equipment, the performance test and the generation of generated spoofing jamming signal. A GPS baseband signal generation and control module based on FPGA (Field Programmable Gate Array) is studied. Mainly through the hardware circuit design and the software code writing, the C / A code / P code is generated by FPGA, and the L _ 1 / L _ 2 carrier wave is generated by the direct digital frequency synthesizer. The multi-channel controllable gain GPS signal is output simultaneously. The test results show that, The output gain is adjustable and the output frequency is controllable. It can provide multi-channel baseband signal and control signal for RF module.
