Direction-finding cross-location(DF-CL) technology is widely adopted in radio monitoring, electronic reconnaissance, radar localization, and communication surveillance due to its conceptual simplicity, ease of implementation, computational efficiency, cost-effectiveness, and robust anti-jamming capabilities.Focusing on ship-aircraft multi-platform collaborative DF-CL,this study proposes a multi-platform two-stage weighted fusion direction-finding positioning algorithm based on fundamental DF-CL principles.This algorithm enhances the utilization rate of multi-platform angle measurement information and the positioning efficiency, and optimizes the weighted fusion DF and positioning process for ship-aircraft platforms.Simulation experiments demonstrate that the proposed algorithm significantly improves the accuracy DF-CL and facilitates engineering implementation for ship-aircraft coordinated cross location.
