SAR对南沙群岛暗礁的成像能力

The SAR Imaging of Nansha Isles' Submerged Reef

介绍了合成孔径雷达（ＳＡＲ）的成像原理及南沙群岛潮流、波浪状况。通过研究潮流、波浪对海表面微尺度波的调制机理，结合两者ＥＲＳ－１ ＳＡＲ 图像论述了ＳＡＲ对南沙群岛暗礁具有成像能力。

This paper introduces SAR imaging principle and status of tidal current and wave of Nansha isles′. According to the research on the mechanism of modulate of microscale wave with tidal current and wave, combined with two ERS 1 SAR images the imaging ability of SAR of Nansha isles′ submerged reef is proved.
