Calculation of beyond visual range air combat all-domain fire field and application of situation threat assessment and assistant decision making

This paper proposes a calculation method for the all-domain fire field for the threat assessment of beyond visual range (BVR) air combat situations. To overcome the drawbacks of conventional situation threat assessment techniques, such as high subjectivity and an inability to meet real-time computing requirements, the all-domain fire field calculation is split into offline single aircraft fire field calculation and online aggregation calculation, taking into account the limitations of missile-based computing resources. Firstly, a BVR air combat simulation environment was established, taking into account the detection error of missile seekers and the delay of servo response. Secondly, based on the Monte Carlo method, considering the deviation of pilot behavior, key decision points for maneuver are divided and control variables with normal distribution are introduced to calculate the success rate. Furthermore, based on the independent probability event formula, the single aircraft fire field is aggregated. Finally, calculate the gradient feature representation model of the entire fire field, and design a decision aiding system for one-on-one beyond visual range air combat scenarios. This work can confirm the all-domain firing field’s conceptual design and provide further evidence for the study of decision-assistance system design and threat assessment techniques for BVR air combat situations.
