摘　　要：　雷达干涉仪和激光高度表广泛应用于地面高度测量,本文首先利用雷达干涉仪确定地面高度,然后再融合激光高度表数据改进雷达测量结果。数据测量结果表明,与仅使用雷达干涉仪测得的数据相比,数据融合获得的高度测量数据更为精确。Interferometric radar and laser altimeter both are widely used for height finding. In this paper, the ground surface elevations are determined first with interferometric radar data, then the data obtained by laser altimeter is fused with the result acquired by the radar to improve the estimate of ground elevations. Measuring result show that the fused data from the two sensors is more accurate than the data obtained from the radar alone.
