摘要 本文基于 SAR相干成像的原理 ,利用当图像分辨率改变时 ,自然景物和人工目标斑点模式变化方式的不同 ,提出了一种从自然景物中识别人工目标的多尺度模型 ,并研究了此模型在不同分辨率图像中的性质及应用。 SAR is a coherent sensing device.When image resolution changes,the speckle pattern of natural clutter and man made objects is typically different.Based on this theory,we develop a novel multiscale model to discriminate man made targets from natural scene,then test this model using SAR images of different resolutions.
