Digital Spectrum Analysis based on DSP and its Applications in Radio Altimeter

文中讨论了一种基于DSP的数字频谱分析方法,并设计完成了用于某新型弹载无线电高度表的数字信号处理应用系统,该系统采用高速DSP芯片TMS320VC5410,可以实时实现高精度的数字频谱分析算法。嵌入了DSP系统的弹载无线电高度表,可以在导弹飞行的高度范围内,实时连续测量导弹的高度数据,并传送给导弹主控计算机,整个系统具有灵活、精度高、体积小、重量轻和工作稳定等优点,静态电缆测试和实际飞行试验的测试结果表明了系统具有较好的测量性能。

In this paper,we present a DSP unit which has been used in an new developed digital radio altimeter. The DSP board is developed based on Digital Signal Processor TMS320C5410 and high accurate and real time spectrum analysis algorithms, so as to make radio altimeter have some good properties such as small size and weight, flexibility and relibility etc. A number of cable line measure results and real flying experiments results are given.
