摘要
为了对雷达信号进行识别,一般先要对其信号参数进行特征提取.雷达信号的参数特征提取一般采用的是等宽直方图法,但由于此法中的分组数一直由人为主观确定,故存在种种弊端.针对这个现象,利用一个定量化的综合评价指标来确定直方图最优分组数,使得直方图的制作更加客观、迅速.最后将由定量化综合评价指标确定分组数的直方图法应用于雷达信号载频参数分析上,仿真实验验证了该方法具有快速、准确和易实现等优点,为此类问题的解决提供了一个方便的工具.
In order to recognize radar signals,the signal parameters are usually taken feature extraction at first.The common method adopted in feature extraction of radar signal parameters is equal-width histogram,but the group number of this method is fixed on artificially,so there are some disadvantages in it.For this problem,a quantified synthetic estimate index is proposed to make sure the best grouping of histogram in this paper,which brings impersonality and speediness to histogram making process.Lastly,the bes...
