摘　　要：星载探测雷达具有全球覆盖、全天候、全天时、不易受到攻击等优点,在预警防御系统中具有巨大潜力。单个星载探测雷达由于俯仰角误差过大,导致其不具备空中目标高度估计能力;准确的目标高度估计对改善目标定位精度及威胁估计能力等具有重要意义。考虑多部星载探测雷达组网,提出了一种基于几何的空中目标高度估计方法,并通过仿真验证方法的有效性。通过仿真比较了雷达探测区域不同位置目标高度估计精度的差别,为组网雷达系统设计等提供技术支撑。Spaceborne detection radars have such advantages as global coverage,all-weather,allday operation capability,invulnerability,etc.,and have great potential in the early warning and defense system.As the error of the pitch angle of a single spaceborne radar is too large,it does not have the ability to estimate the height of aerial targets;however,accurate target height estimation is of great significance to improve target positioning accuracy and threat evaluation capabilities.The networking of multiple spaceborne detection radars is considered,and a geometry-based aerial target height estimation method is proposed.The effectiveness of the proposed method is verified by simulations.In addition,the differences in the estimation accuracy of target heights at different positions in the radar detection area are compared through simulation,providing technical support for the design of networked radar systems.
