摘要
针对传统的扩跳频信号源智能化程度低、携带不方便、效率低下等问题,设计了一种基于FPGA+AD9915的体积小、功耗低、精度高的扩跳频信号源。使用Verilog语言在Quartus Ⅱ软件开发平台上编程实现系统软件设计,在FPGA芯片内完成基带信号处理、跳频码产生和中频调制,并通过FPGA实现对AD9915和数模转换芯片的控制,最后混频实现扩跳频信号的产生。测试结果表明系统有较好的性能,可以满足电台测试时对跳频速率、频率间隔等方面的要求。
Aiming at the problems that the traditional DS/FH signal source is less intelligent, inconvenient to carry and inefficient, a DS/FH signal source with small volume, low power consumption and high precision was designed based on FPGA + AD9915. The system software was designed with Verilog language by using Quartus Ⅱ software development platform. The FPGA chip was used to realize the baseband signal processing, frequency hopping code generating and intermediate frequency modulating, and the control of AD9915 and digital-analog conversion chip was also realized through FPGA. Finally, the DS/FH signal source was generated by mixing frequency. The test results show that the system has better perfbrmance and can meet the test requirements on frequency hopping rate and frequency interval.
