Abstract重跟踪是海洋雷达高度计1B级数据处理中的重要内容,依靠重跟踪可进一步精确提取测量信息,在重跟踪中利用雷达系统的点目标响应和加权窗进行数据校正十分重要,本文提出了一种利用点目标响应和加权窗进行雷达高度计重跟踪的新方法,在该方法中利用点目标响应和星上加权窗重新构造了重跟踪时使用的信号模型,从而有效地提高了重跟踪的精度.本文利用该方法对SZ-4高度计的数据进行了处理,并将处理结果分别与同期的ERS-2高度计测量数据和海面浮标数据进行了对比,对比结果显示该方法对参数提取效果有显著改善.
Other AbstractOcean retracking is an important step for the 1B data processing of ocean radar altimeter. We can obtain precise estimates of ocean parameters by ocean retracking. It is important to use point target response (PTR) and weight window to correct these estimates . This paper proposes a new approach to perform ocean retracking for radar altimeter with PTR and weight window ,which are used to reconstruct the waveform model of ocean retracking. We processed the data of SZ24 radar altimeter with the new approach and compared with those of ERS22 and buoys in the same period. The results show that our approach is effective for improving the accuracy of the estimates .
