摘要
SAR图像峰值本质上对应于目标和 (或 )背景杂波的散射中心 ,本文研究了由 SAR图像提取目标峰值的方法 ,分析了目标峰值随目标方位角和仰角的变化 ,结果表明 ,目标 SAR图像峰值在一定的方位角和仰角变化范围内具有一定的“稳定性”。这说明 ,利用峰值特征进行
Peaks of SAR image corresponding to target′s and(or) background clutter′s scatter center in nature. The method of peak extraction from SAR image is studied in this paper, also the variability of target′s peaks with target orientation and depression angle is analyzed, the results show that the peaks of target in SAR image have some stability with target′s orientation and depression variability. So it′s feasible to recognize target from SAR image using peak feature.
