The Guidance Method of UAV with Sensor Failure Based on Multi-UAVs Cooperation

In today’s complex antagonistic environment, UAVs are often subject to infrared, electromagnetic or compound interference, resulting in sensors failure. This problem has attracted much attention. In this paper, a third-party cooperative guidance method is designed, which enables the UAV with failed sensors to convert the direct detected data of other sensors into guidance instructions. A data fusion method based on fuzzy set theory is adopted to reduce the propagation error of calculation. This method does not need the prior information of measurement equipment. Finally, simulations are performed in a typical combat mode for qualitative and quantitative analysis. The results show that the guidance accuracy of cooperative guidance is not lower than that of single UAV active guidance, and the cooperative guidance method can replace the function of original sensor.
