由于多径回波信号的干扰，雷达对低空目标俯仰角的实时测量很难达到靶场外弹道测量的精度要求。结合目前靶场在装雷达系统，研究了掠海巡航飞行低空目标的俯仰角事后提取问题，为了提高低空目标俯仰角的测量精度，应用动态偏差补偿技术从雷达系统实时存储下来的视频信号中提取低空目标俯仰角参数。结果显示，动态偏差补偿技术可以显著改善俯仰角测量精度，为靶场试验决策提供依据。

In the presence of sea-surface multi-path mono-pulse radar measure a low elevation target is difficulty, and its precision cant satisfy the requirement of ballistic trajectory measurement in shooting range. We apply the dynamic bias compensation algorithm calculate the elevation of low-altitude after measurement from the saved video signal by the radar system used in navy range. Result indicates dynamic bias compensation is effective and feasible in the off-line elevation extraction and it can remarkably improve the precision of elevation measurement. Then offer the gist for experimentation decision-making.
