采用ADS(Advanced Design System)的EDA工具实现了对某实时测向系统的高效仿真,其中模拟电路部分采用软件自带的参数化模块来定义各器件性能,数字电路各子模块则可采用面向芯片(DSP、FPGA)的算法模块进行建模,保证了整个系统仿真的完整性和真实性;最后从系统模拟电路接收灵敏度和数字电路参数设置等方面分析了该系统的测向性能。 The EDA tool of ADS (Advanced Design System) is used to realize the efficient simulation of a real-time direction finding system. The analog circuit part uses the parametric module of the software to define the performance of each device. The digital circuit sub-module can be used for the chip (DSP, FPGA) algorithm module to ensure the integrity and authenticity of the entire system simulation; Finally, from the system analog circuit receiving sensitivity and digital circuit parameter settings and other aspects of the system’s directional performance.
