摘要
研究了宽带雷达距离像检测问题。针对宽带雷达目标的距离像姿态敏感性,将模型定阶准则引入到距离像长度估计问题中,提出了一种基于信息熵准则的自适应积累检测算法。仿真结果表明,与基于平均信噪比最大准则的自适应积累检测相比,算法的检测性能更优。
The problem of range profile detection for wide band radar is studied. For the sensitivity to range profile＇s relative poses,a model order selection criterions is presented to estimate the length of range profile. And an adaptive integration detection algorithm based on Akaikeinformation criterion for wide band radar is proposed. The results of simulation experiments show that the detection performance of the algorithm proposed will be better than that of the algorithm based on maximum average SNR criteria.
