Near-distance air combat automatic decision-making method based on single-step prediction matrix gaming

Abstract

The invention discloses a near-distance air combat automatic decision-making method based on single-step prediction matrix gaming. The method comprises the following steps: step 1, erecting a six-degree-of-freedom nonlinear unmanned combat air vehicle control law structure; step 2, initializing a matrix gaming chessboard; step 3, according to the gaming chessboard, carrying out single-step prediction calculation; step 4, calculating a payment function matrix; step 5, carrying out strategy selection through a minimax algorithm; step 6, updating a six-degree-of-freedom plane kinetic and dynamic equation; and step 7, determining whether an air combat termination condition is reached. The method has the following advantages: compared to a three-degree-of-freedom particle model, the actual application value is higher. At the same time, a conventional matrix gaming method based on a maneuver library is changed to be based on a maneuver library of an instruction model, what is needed is only prediction of a step length of a single step, the decision-making time is effectively reduced, the requirement for real-time performance of air verification is satisfied, the method can be better adapted to complex dynamic baffle field environment change, and the combat capability of an unmanned combat air vehicle in a near-distance combat is improved.

Description

【Technical field】 [0001] The invention is an autonomous decision-making method for close-range air combat based on a single-step prediction matrix game, and belongs to the field of autonomous air combat decision-making for unmanned aerial vehicles. 【Background technique】 [0002] With the improvement of the performance and weapons of unmanned combat aircraft, unmanned combat aircraft makes full use of various technological achievements in the era of information technology revolution, and further develops in the direction of a new information weapon system with higher performance and higher autonomous combat capabilities. [0003] According to the classification of air combat combat distance, it can be divided into two air combat stages: over-the-horizon air combat and close-range air combat. Due to the hit probability of missiles and electronic interference from enemy aircraft, unmanned combat aircraft may appear If the attack fails, the two sides need to enter the close com...

Problems solved by technology

However, the movement of a real unmanned combat aircraft in space should also include the change of attitude angle, and due to the rapid change of the battlefield situation, the tactical actions generated by the decision-making often need to be switched to the next action if they cannot be effectively executed
