Abstract：Aiming at the target location problem in the case of non-cooperative moving opportunity transmitter, a single-re?ceiver passive coherent location algorithm based on cross-fusion Cubature Kalman filter is proposed. First, a mathematical model for the location of the single-receiver passive coherent location based on non-cooperative transmitter is established. Secondly, Cubature Kalman filtering is used to perform prediction and update of the state of the target and the transmitter. Aiming at the error transfer phenomenon occurring in the update process, based on the idea of multi-source information fusion, a state estimation cross-fusion model is proposed. The simulation results show that the proposed method can effectively reduce the influence of transmission error and accelerate the convergence speed while improving the positioning accuracy.
