Abstract： In view of the possible false alarms and missed detections in the single data processing results of spaceborne passive detection，which leads to the complexity of multiple detection association processing，multi-radiation source target processing method based on the Lagrange relaxation algorithm is proposed.By Lagrange constraint relaxation and parameter set association，the original multi-dimensional assgnment（SDA）problem is transformed into a lower-dimensional data association problem，thereby eliminating the association ambiguity in the tracking processng of multi-radiation source targets and improving the association accuracy of multi-radiation source targets. Through simulation verification，accurate association and tracking of multi-radiation source targets can be achieved under dense scene conditions.
