A Geometry-based Algorithm for Estimating the Height of Aerial Targets in a Network of Spaceborne Detection Radars
Spaceborne detection radars have such advantages as global coverage,all-weather,all-day 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 a-bility to estimate the height of aerial targets;however,accurate target height estimation is of great sig-nificance 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 estima-tion method is proposed.The effectiveness of the proposed method is verified by simulations.In addi-tion,the differences in the estimation accuracy of target heights at different positions in the radar de-tection area are compared through simulation,providing technical support for the design of networked radar systems.
