摘要
由于雷达的侧视投影特点,地形的起伏将引起较大的投影差,利用在多项式纠正的基础上引入投影差改正来纠正泰山地区机载SAR影像。试验表明:此方法在纠正高山地区影像时具有较高的精度。在文章的最后对山区雷达影像处理中的几个问题进行探讨。
Because of the side-looking properties of radar, the height variance of the target will cause larger displacement in the image. It uses a method which adds the displacement caused by the height variance to the polynomial method to rectify the air-borne SAR images of Taishan. And experiment indicates that this method has a high precision in rectifying the air-borne SAR images of mountainous areas. In the end, several problems related to the mountainous area air-borne SAR image processing are discussed.
