Abstract星载雷达高度计是很有应用价值的微波遥感器,我国将于近年发射海洋二号卫星,高度计是其主载荷.在航天环境中,硬件性能的不理想会带来测高误差.通过在星上进行内定标工作能够较好地修正这些误差.首先描述了内定标的主要任务,推导了内定标模式中的信号流程.然后,总结了目前国内外星载高度计的内定标技术,对它们进行了分析和比较,选择了一套内定标方案,对延时和衰减参数进行了工程设计,并分析了双频和多带宽体制对内定标的影响.最后,作者对内定标模式1中产生的误差源及其对测高的影响进行了分析,并结合TOPEX参数对内定标模式2对测高性能的改善进行了定量研究.
Other AbstractRadar alt imeter is one of the majo r payloads on m icrow ave remo te sen sing. An altimeter will be embarked on the upcom ing HY22 satellite.In-orb it in stabilities will occu r in the radar system due to ageing effects,temperatu refloats,and space radiat ion s and so on.In ternal calib rat ion s are applied to solve this problem.In th is paper the au tho rs describe the task s of in ternal calibration and compare the two main calib rat ion schemes, and choo se the second for engineering design.Then the au tho rs design the at tenuat ion and delay parameters of the calib rat ion channel.The au tho rs also analyze the error sou rcesoccu rring in calib rat ion channels.
