摘要
雷达信号数字脉冲压缩处理主要采用时域和频域两种方法来实现。在专用DSP芯片大量用于数字脉冲压缩系统的同时,高性能的通用DSP芯片将使系统更加灵活。该文讨论了采用专用DSP芯片的数字脉冲压缩时域处理系统与频域处理系统,较完整地进行了实时系统测试,并通过计算机仿真,结合最新发展的通用DSP技术,对两种处理方法作出了较为全面的分析与比较。
Radar signal digital pulse compression processing can be realized mostly by time-domain and frequency-domain methods. The special-purpose DSP chips have been used for the digital pulse compression processing systems widely. At the same time, the general-purpose DSP of high performance will make systems design more agile. The digital pulse compression time-domain processing system and frequency-domain processing system with the special-purpose DSP chips have been developed. On the basis of the real-time testing results obtained and through computer simulating, we made relatively overall analysis and comparison between these two methods, using the current technology of the general-purpose DSP.
