BEPERS-88是一次广泛的关于合成孔径雷达（SAR）在波罗的海海冰遥感中的应用的实地活动。进行这一实验是为了研究在波罗的海咸冰情况下使用ERS-1号卫星合成孔径雷达（和雷达高度计）的可能性。加拿大遥感中心CV-580 C/X波段合成孔径雷达进行了飞行，并进行了广泛的验证方案。这些数据已被用于SAR图像分析、后向散射调查、海冰上空SAR的地球物理验证以及SAR在业务冰信息服务中的潜力评价。结果表明，SAR可以用于区分冰和开放水域，划分冰的类型，量化冰脊强度，并确定冰漂移。作为一种业务工具，合成孔径雷达有望成为NOAA图像和地面实况的一个极好的补充。
Abstract BEPERS-88 was an extensive field campaign on the use of Synthetic Aperture Radar (SAR) in sea ice remote sensing in the Baltic Sea. This experiment was performed in order to study the possibilities of using the ERS-1 satellite SAR (and radar altimeter) in connection with the brackish ice in the Baltic Sea. The Canada Centre for Remote Sensing CV-580 C/X-band SAR was flown and an extensive validation programme was carried out. The data have been used for SAR image analysis, backscatter investigations, geophysical validation of SAR over sea ice, and evaluation of the potentials of SAR in operational ice information services. The results indicate that SAR can be used to discriminate between ice and open water, classify ice types into thrcc categories, quantify ice ridging intensity, and determine the ice drift. As an operational tool SAR is expected to be an excellent complement to NOAA imagery and ground truth.
