A study on formation configuration design for long rang anti-radiation loitering munitions

Aiming at improving the target positioning accuracy, the formation configuration of anti-radiation loitering munitions is optimized. Firstly the time difference measuring error and positioning error of the loitering munitions are analyzed and the error propagation model is developed. Then the formation configuration design model is established based on the proposed time difference localization algorithm and the formation flying boundary conditions. Finally, considering the nonlinear features of optimization function for configuration optimization design, the genetic algorithm is introduced to obtain the optimal configuration. The simulation results show that, compared with the traditional formation configurations, the optimization design of configuration can acquire higher estimation accuracy of target position. Besides, the designed configuration has strong robustness. High accuracy estimations of target position can be obtained under a wide range of target position changes.
