摘要
本文依据山东蓬莱附近海区１９９２年４月１９日的ＥＲＳ－１ＳＡＲ图像，分析了该海区的水下地形并探讨了水下地形雷达成像机理。分析结果显示，ＳＡＲ图像较好地揭示了该海区四人洲、潮待洲、新井洲等水下地形。研究指出，流经水下地形的潮流对海洋表面波的水动力调制是水下地形ＳＡＲ成像的主要机理。
One ERS-1 SAR image on 19 April 1992 off the north coast of Penglai has been analyzed. The image reveals underwater sand waves of Sirenzhou, Chaodaizhou and Xinjinzhou.The SAR imaging mechanism of these bathymetric features is also discussed in this paper. It isshown that they were imaged via tidal-currents interactions.
