本文从建立目标多卜勒频率的数学模型着手,根据雷达的重复频率等参数和雷达所测得的已知模糊数椐,导出分辨速度模糊的一种算法。这种算法具有简明直观、运算量小、易于用程序实现等优点。它特别适合于具有FFT信号处理机的低、中脉冲重复频率系统的数字雷达。文章最后还列举了一些具体例子。
In this paper, a mathematical model of the target Doppler frequency is established. Based on the parameters such as the repetition frequency of the radar and the known fuzzy number 雷 measured by the radar, an algorithm of resolving the velocity ambiguity is derived. This algorithm has the advantages of concise and intuitionistic, less computation, easy to implement by program and so on. It is particularly suitable for digital radar systems with low and medium pulse repetition frequency systems with FFT signal processors. Finally, the article lists some specific examples.
