摘要
针对脉冲分选聚类中存在的问题,引入熵的概念,定义了PRI(脉冲重复间隔)熵,给出了雷达脉冲序列之间合并的PRI熵判据。并在此基础上提出了新的雷达信号聚类方法。采用先分选后合并的思路,通过计算合并前后PRI熵是否减小来判断是否对序列合并。通过仿真验证该方法解决增批问题的有效性。
The entropy is applied for problems of radar pulses sorting and clustering. PRI （Pulse Repetition Interval） entropy is defined, and PRI entropy criterion is given. A new approach to radar signal clustering is presented based on PRI entropy. This method includes sorting and combination. In the method, whether the PRI entropy decrease or not, determines the radar pulses combination. At the end, the simulated experiments show that the problems in radar pulses sorting and clustering could be resolved with the new approach.
