高分辨率SAR圖像目標峰值提取及峰值穩(wěn)定性分析

Targets Peak Extraction from High-Resolution SAR Image and Peaks Stability Analysis

  • 摘要: SAR圖像自動目標識別的一個主要途徑是通過目標峰值序列的匹配進行識別。該文提出了SAR圖像的通用高斯峰值模型，并根據(jù)該模型設(shè)計了SAR圖像目標峰值提取方法，進而利用實測目標數(shù)據(jù)分析了目標峰值對于目標方位角，雷達俯仰角以及目標結(jié)構(gòu)等目標配置條件變化下的穩(wěn)定性。結(jié)果表明，目標SAR圖像峰值對于目標的配置條件變化具有一定的穩(wěn)定性，這說明，利用峰值特征進行SAR圖像目標識別是可行的。
    Abstract: Peak sequence matching is a important approach to SAR ATR. A general Gaussian model for peak is given in this paper and the extraction method is designed based on this model. Utilizing actual target database, the variability of targets peaks with target orientation, configuration and depression angle is analyzed. The results show that the peaks of target in SAR image have some stability with targets orientation, configuration and depression variability. So it is feasible to recognize target from SAR image using peak feature.
