针对超宽带合成孔径雷达在树林区域探测隐蔽目标的应用场合,研究了树干杂波的统计特性。运用实验数据从幅度直方图拟合、高阶统计量和杂波统计模型识别几方面分析了VHF/UHF波段超宽带合成孔径雷达树干杂波的统计特性,得出了以K-分布为杂波模型的目标检测算法才能获得较佳的检测结果的新结论。
Aiming at the application of UWB synthetic aperture radar in detecting hidden targets in the forest area, the statistical characteristics of trunk clutter are studied. The experimental data are used to analyze the statistical characteristics of the trunk clutter of VHF / UHF band UWB synthetic aperture radar from the aspects of amplitude histogram fitting, high-order statistics and clutter statistical model identification. The K- The model of the target detection algorithm to get a better conclusion of the new test results.
