摘要
采用等精度测频法及相应的数字信号处理IP核,以ALTERA公司Cyclone II系列EP2C70F896C6N FPGA为核心实现了某型卫星陀螺组合X、Y、Z轴3个方向上的角速度信号、温度信号的测量处理系统的设计。实验结果表明基于FPGA的数字频率信号处理系统相对于以往数字频率信号处理电路具有高精度、高集成度、高速和高可靠性的特点,满足航天系统对信号处理电路设计高标准的要求。
This paper introduced how to use ALTERA Cyclone II series FPGA EP2C70F896C6N with equal precision frequency measurement method and corresponding digital signal processing IP core,and then completed design of the measurements and processing system about three directions angular velocity and temperature signals of a certain type satellite＇s Gyro X,Y,Z axis.Experimental results show that the FPGA-based digital frequency signal processing system has a high accuracy,high integration,high-speed and high reliability features compared with the previous digital frequency signal processing circuit,meets the signal processing circuit design for high standards in space systems.
