Conventionally, estimating the transmitter’s position relies on two-step localization methods. Compared to conventional two-step localization methods, direct position determination (DPD) is a technique with superior performance. In most localization scenarios, shortwave and ultrashort wave signals are mostly used. But in reality, the propagation of shortwave signals is usually affected by ionospheric reflections, and the signal strength of the ultrashort wave signal will decay rapidly with the increase of distance. Therefore, finding a method that can cooperate with the two kinds of signals is the key to improving the localization accuracy of the DPD method. This study considers the shortwave signals propagated by ionospheric reflections, and the ultrashort wave signals propagates through line-of-sight. Furthermore, this paper proposes a DPD method that cooperates with the 2-dimensional DOAs (Direction of Arrival) of shortwave signals and the DOA and FOA (Frequency of Arrival) of ultrashort wave signals. To achieve decoupled positioning of multiple transmitters, this paper uses the idea of Weighted subspace data fusion (SDF). The simulation results show the proposed DPD method has good performance.
