摘要
本文简要介绍了海洋雷达高度计的工作原理，分析了定时抖动、时钟精度及回波中的固有噪声等因素对高度测量造成的影响，讨论了“全去斜坡”等接收系统的关键技术，研制出了中分辨率机载海洋雷达高度计接收系统，并且与发射系统联调取得了成功。系统分辨率达到了５ｎｓ的设计需求。
This paper introduces briefly the measurement principle of the Radar Altimeter.The altitude measurement error caused by timing jitter,clock accuracy and inherent noise in echo signal is analyzed.The key technique included“Full-deramp”and the method of using filter bank to seperate range returns is discussed.We have developped a Middle-Resolution Ocean Radar Altimeter Receiver System and successed in the experiment combining with the transmitter system. The design requirement of 5 nanosecond system resolution is achieved.
