摘要
本文设计使用射频模块和FPGA开发板搭建了完整的信号捕获解算平台,开发验证的过程中需要采集设计中各个阶段中间数据,在开发平台的基础上实现中间数据的采集和分析。基带模块接收的射频数据及其中间数据,速度快、体量大,对数据采集存储难度比较大。本设计在复用捕获解算平台的基础上提出对射频数据的采集方案,对中间数据读取、串并转换、内部存储、外部读取,准确的完成既定目标,通过复用平台保证采集数据和设计中间数据的环境变量的一致性。采集的射频数据既可以充分的验证射频模块的正确性,同时可以在收集的卫星信号的基础数据建立仿真对比验证捕获算法。
In Based on RF module and FPGA development board, a signal capture platform is constructed about baseband receives RF data. In the development verification process, the intermediate data in each phase of the design should be collected forcomparativing base on the same boad. The RF data and the intermediate data is fast and the total amout is large so that the data collection is difficult. The scheme of RF data acquisition is put on the original platform.Achieved on the middle of data read,serial and conversion, internal storage, external read. The RF data and the intermediate data on the original platform ensured the consistency of environment variables.RF data can verify the RF module fully, and alse verify the capture algorithm by contrast simulation.
