To reduce the spherical error probability (SEP) of the traditional unmanned aerial vehicle (UAV) ranging-based target localization algorithm, and to analyze the target locatable duration. This paper proposes a target ranging localization algorithm based on solving nonlinear equations and total least squares method, and the influence factors on circular error probability (CEP) and SEP are analyzed by the simulation, the four high reference value conclusions are summarized. The target localization flight experiment is carried out to verify the designed localization algorithm’s effectiveness and precision. The target locatable duration of the UAVs formation straight flight target localization process is analyzed by geometric analysis, and the corresponding calculation formula is given. The simulation results prove that the algorithm proposed has lower CEP and SEP than the traditional method. The flight experiment shows that the designed algorithm has good accuracy in engineering applications.
