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。 A linear frequency modulation continuous wave altimeter based on digital SOC platform is introduced. SOC is built in XILINX FP-GA, mainly including modules such as CPU, interrupt control, digital signal processing module and CAN bus communication protocol. All functional modules are mounted on the PLB bus. Altimeter uses SOC for signal processing, target height search and tracking mode control, and communication. The altimeter with this design has the advantages of high integration, simple structure and high reliability.
