SOC在线性调频连续波高度表中的应用

摘要

介绍了一种基于数字化SOC平台的线性调频连续波高度表。SOC在XILINX FP-GA中搭建实现,主要包括CPU、中断控制、数字信号处理模块和CAN总线通信协议等模块,所有功能模块都挂接在PLB总线上。高度表使用SOC实现信号处理、目标高度搜索和跟踪模式控制以及通信等功能。采用这种设计的高度表具有集成度高、结构简单和可靠性高等优点。%Discusses a kind of linear frequency continuous wave altimeter based on digital frame SOC; SOC which consists of CPU, interrupt controller, DSP, CAN BUS protocol and so on is built in XILINX FPGA. All function modules are connected to the PLB bus. Altime- ter carries out height searching and tracking control and communication by SOC. It has the specialties of high integration, simple structure and high stability.
