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。

Abstract

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.
