For solving the effectiveness evaluation problem of UVA under uncertain weighting conditions, put forwards the advanced UVA comprehensive evaluation method under uncertain information conditions. Based on the UAV autonomous control method, establish more comprehensive UAV effectiveness evaluation model. Through analyzing UAV reconnoiter effectiveness, attack effectiveness and autonomous control effectiveness, and use Matlab simulation evaluation to verify the method. The simulation method shows that the calculation of method is easy and the analysis result is intuitive and simple, it has validity and suitability.
