Threat evaluation method for aerial target in beyond-visual-range air combat

Abstract

The invention provides a threat evaluation method for an air target in an over-the-horizon air combat, and relates to the technical field of threat evaluation in the over-the-horizon air combat. The method comprises the steps of firstly establishing a missile model, and calculating flight data of a missile carried by a target enemy plane; determining a turning angle when the aircraft escapes according to the azimuth angle of the enemy aircraft, and further determining an escape route and a folded escape distance of the aircraft; determining the turning angle and the turning time of the enemy plane according to the azimuth angle of the enemy plane and the speed vector direction of the enemy plane; judging whether the aircraft is within the range of the enemy missile or not, and judging theattack result of the enemy aircraft to the aircraft and the total attack time by combining the flight speeds of the enemy aircraft and the aircraft; and finally, determining a threat evaluation valueof the enemy plane to the aircraft according to an attack result of the enemy plane to the aircraft. According to the method, energy is used as a basis, time is used as a unified dimension, and the judgment precision of absolute threat evaluation is effectively improved; and the output quantity units are unified, so that the judgment precision of relative threat evaluation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of threat assessment in over-the-horizon air combat, in particular to a threat assessment method for air targets in over-the-horizon air combat. Background technique [0002] The purpose of fighter threat assessment in over-the-horizon air combat is to confirm the threat level of the target fighter (referred to as the enemy fighter) to our fighter (referred to as our fighter). The judgment accuracy of decision-making can effectively improve the air combat rate, and has been widely used in the fields of fighter beyond visual range air combat (BVR), electronic countermeasures (ECM) and command and control (C4I). Due to the many and complex variables that need to be considered in air combat threat assessment, most of the current research results set strict restrictions on the initial conditions, and there are few general-purpose over-the-horizon threat assessment methods, and the assessment accuracy is often no...

Problems solved by technology

Its disadvantages are twofold: First, it introduces a large number of irrelevant parameters. Even if the weighting accuracy is improved, logical conclusions cannot be obtained, and it is not advanced.

The second is that the parameters used are too complicated, and it is usually impossible to obtain comprehensive intelligence in air combat, which may cause the algorithm to be interrupted or even collapsed, and the versatility is poor
