中文摘要: 推导了一般情况下激光站为星载雷达高度计进行绝对定标的数学模型,并进行了仿真验证和误差分析,对高度计定标精度进行了定量评估。利用Corsica定标场区中Grasse激光站对Jason-2卫星定轨的实测数据进行了分析,取得了满意的结果。
英文摘要: Space-borne radar altimeters can measure a majority of the global sea surface height within an accuracy of few centimeters, but there are various errors in altimetry measurements, so absolute calibration activities are necessary. Ground laser stationshave rangeaccuracies of better than 1cm, so can be combined with the space-borne laser reflector array (LRA)included in independent calibration. Ageneral model for laser calibration for space-borne altimeter is deduced, one not previously presented in the relevant publications. Afterwards, simulations and error analysis were executed based on the model, and the calibration precision was estimated quantitatively. In particular, the Grasse laser observations (actual laser echoes from the Jason-2 satellite LRA) in the vicinity of the Corsica calibration site were analyzed, the results were promising. Finally, the contributions of the laser station in the calibration site are summarized, and the benefits of simultaneouslyoperating laser station and GNSS buoy configuration are discussed. The constructionand performance assessment of China's forthcoming satellite altimeter calibration site will benefit from the study detailed.
