多传感器组网的航空目标三维定位算法
Multi-Sensor Network-Based Three-Dimensional Positioning Algorithm for Airborne Targets
摘要
Abstract
Accurately locating aviation targets in three dimensions presents formidable challenges owing to their high-speed movements and expansive maneuverability compared to ground targets.This paper presents a three-dimensional posi-tioning algorithm for aerial targets based on a multi-sensor network.Using two high-altitude unmanned airships,each equipped with an optical sensor device,and UAV-shipborne bistatic dual-coordinate radars,the study focuses on achieving precise positioning of aerial targets through multi-platform collaboration.This approach addresses the limitations of tradi-tional methods,which often fail due to the incomplete measurement dimensions of individual sensors,preventing accurate independent determination of the target's 3D spatial position.Our approach begins with the introduction of a two-level point-trace correlation algorithm grounded in spatial alignment,leveraging both angle and distance to effectively correlate non-dimensional measurements from multiple sensors.Subsequently,we establish the initial positioning points of the target on each spatial measurement model through the construction of target guidance points,employing techniques such as ellip-soidal space Nelder-Mead Euclidean distance optimization and azimuth space projection.Finally,precise positioning points of the target are obtained through the utilization of unscented transform and homologous data compression.Simulation re-sults demonstrate the efficacy of our algorithm in achieving stable correlation of radar-dual optical measurement data,even in scenarios where dimensionality is lacking.Notably,our algorithm achieves an optimal positioning error for aviation tar-gets as low as 115.7 meters.关键词
