| Abstract(in English) | The Unmanned aircraft system (UAS) has been researched and developed as a temporal communication system for the emergency and rescue service in disaster such as earthquake, serious accidents, and so on. In the typical UAS model, several numbers of unmanned aerial vehicle (UAV) with the velocity of 40 to 100 km/h and the altitude of 150 to 1,000 meters shall be applied to the provision of wide service coverage. The UAV is composed of a transmitter and a receiver so as to transfer the signals from terrestrial stations and terminals. Therefore, Doppler shifts are occurred in the carrier frequency of the transmitted and received signals by a change in line-of-sight velocity between the UAV and the terrestrial terminal. By observing multiple Doppler shift values for different UAVs, it is possible to detect the position of the user who possesses a communication terminal for the UAS service. In order to evaluate the accuracy of the position detection method using multiple UAVs, we have been conducted computer simulations under several types of flight models. From the simulation results, it was confirmed that the positioning accuracy depends on the number of UAVs, location of UAVs, and other setting parameters for UAVs. In this study, an influence of location relationships among multiple UAVs, and relationship between UAVs and a user terminal against the position detection accuracy is investigated using Doppler frequency distribution map at first. Secondly, the positioning accuracy of the position detection method using two UAVs which flying circularly is evaluated by changing the initial positon of the UAVs when the control error of UAV is existed. |
