中文摘要：

天波超视距雷达通常采用距离一多普勒处理来检测海面上的目标。距离一多普勒处理可以获得目标的斜距和多普勒频率，而不能获得目标的高度信息。该文提出一种基于匹配场处理的算法来估计目标高度，算法利用单个驻留周期的回波数据来进行估计。仿真表明，在给定的仿真场景下，目标高度估计精度可达2000m左右。与已提出的对数似然函数算法相比，该算法具有更好的稳健性。

英文摘要：

Skywave over-the-horizon radar usually detects targets over the sea surface using Range-Doppler （RD） processing. RD processing can obtain the slant range and Doppler frequency of the target, but the altitude can not be derived. An algorithm based on the matched-field processing is proposed to estimate the target＇s altitude. The algorithm uses the return signal in a single dwell. Simulation result shows that under the specified simulation scenario, the altitude estimation error is within 2000 m. Comparing with the log likelihood function algorithm, the proposed algorithm has better robustness.
