摘要
最优分组是直方图法中的一个关键问题,对直方图法的有效性起着决定性的作用。在研究直方图法提取离散型雷达信号参数特征的基础上,根据信息熵的物理意义及其基本性质,提出一种基于熵的最优分组判定准则,并用仿真实验验证了该判定准则的有效性。
The optimal classification is a key problem in histogram and has decisive effect on histogram. Through studying feature extraction of discrete radar signal parameter using histogram, the optimal classification criterion based on entropy is proposed according to the physical meaning of entropy and its basis characteristics, and a simulation experiment shows the criterion is effective.
