| 摘 要： | 阐述了脉冲多普勒(PD)雷达中重复频率(MPRF)工作方式的工作原理以及现有的经典设计方法,并对现有中重复频率设计方法在受到干扰时的缺点进行了分析。通过分析给出了一种基于假设失效的PD雷达MPRF工作方式的优化设计方法及系统设计实例。该方法通过对假设失效的情况下系统的优化,增强了系统在部分工作方式失效情况下的性能,提高了工程实践中系统在受到干扰时的性能。

| Abstract: | In this paper,the principle and classical design methods of medium pluse repetition frequency(MPRF) mode are reviewed,and the disadvantage of the classical MPRF waveform design methods is analysed.With the help of analysis,an optimized MPRF design method based on hypothesis-failure is proposed,and a system design example is given.The method considers the hypothesis-failure in the design phase to improve the performance when parts of the system fall,so that it improves the performance under interface in real... |
