摘要: 概述了某型航管二次雷达(SSR, Secondary Surveillance Radar)模拟器的设计思想和基本结构,详细论述了TMS320F206的基本结构与特点,着重探讨了该数字信号处理器(DSP, Digital Signal Processor)芯片在系统数据交换和接口数据管理与控制中的功用,并指出了系统软硬件调试中需要注意的一些问题.经过对SSR信号处理机的调试,证明设计达到了预想效果.Abstract: The design idea and fundamental structure of a SSR(secondary surveillance radar) signal simulator are presented. The structure and characteristic of TMS320F206, a kind of 16-bit fixed-point DSP(digital signal processor), are introduced and the function of the DSP in the data-exchanging, control of the system and the process of the I/O port data is discussed in detail. The problems that should be paid attention to in the process of system-debugging are also presented. The expected result has been acquired after the debug of the SSR signal-processing unit.
