Speech Title: Research on key technologies of collaborative direct position determination of sea-aero targets based on distributed arrays

Abstract: High-precision positioning for high-value sea-aero targets (including ships, aircraft, unmanned aerial vehicle, etc.) has important practical significance. This report combines the direct-position-determination (DPD) technology with the collaborative processing idea, and focuses on the key technologies of collaborative DPD for sea-aero targets based on distributed arrays. Aiming at the characteristics of sea-aero target location scenario, this report proposes four kinds of collaborative processing methods, which include the methods making use of the modulation mode of the emitter signal; the methods utilizing the spatial correlation of target group; satellite-ground collaborative positioning methods; and the methods applying the measurement information from the calibration sources. For each kind of collaborative location methods, we construct the distributed array model and propose the collaborative DPD methods. Additionally, the location performance of the new methods is verified by simulation experiments. Theoretical and simulation results show that the collaborative DPD methods can significantly improve the positioning accuracy for sea-aero targets.
