Abstract: Beyond-visual-range (BVR) engagement becomes more and more popular in the modern air battlefield. The key and difficulty for pilots in the fight is maneuver planning, which reflects the tactical decision-making capacity of the both sides and determinates success or failure. In this paper, we propose an intelligent maneuver planning method for BVR combat with using an improved deep Q network (DQN). First, a basic combat environment builds, which mainly includes flight motion model, relative motion model and missile attack model. Then, we create a maneuver decision framework for agent interaction with the environment. Basic perceptive variables are constructed for agents to form continuous state space. Also, considering the threat of each side missile and the constraint of airfield, the reward function is designed for agents to training. Later, we introduce a training algorithm and propose perceptional situation layers and value fitting layers to replace policy network in DQN. Based on long short-term memory (LSTM) cell, the perceptional situation layer can convert basic state to high-dimensional perception situation. The fitting layer does well in mapping action. Finally, three combat scenarios are designed for agent training and testing. Simulation result shows the agent can avoid the threat of enemy and gather own advantages to threat the target. It also proves the models and methods of agents are valid and intelligent air combat can be realized.
TL;DR: The solution of the ATDDG provides the instantaneous optimal heading angles for each agent playing the game in order to achieve their objectives and the assumption of simple motion dynamics of the agents yields their optimal headings which is adequate in a beyond visual range engagement.
Abstract: A particularproblem in aerospace control and applications is the active target defence differential game (ATDDG), where an attacker missile tries to capture a target aircraft which is significantly slower than the attacker. A third agent is a defender missile which is fired by the Target's wingman. The defender's mission is to intercept the attacker in time to enable a successful target evasion and its survival. The problem is naturally posed as a zero-sum DG. The target and the defender form a team; their objective is to determine a cooperative strategy to maximise the terminal separation between the target aircraft and the point where the Attacker missile is intercepted by the Defender missile. The Attacker is the opposition and its task is to devise its own strategy to minimise the same terminal distance. The solution of the ATDDG provides the instantaneous optimal heading angles for each agent playing the game in order to achieve their objectives. Most importantly, the agents' strategies are state feedback laws. The assumption of simple motion dynamics of the agents yields their optimal headings which is adequate in a beyond visual range engagement, as it is currently envisioned to be the pertinent operational scenario.
TL;DR: In this paper, a method and system for providing navigational data required to guide an air-to-air missile to a target is presented, where the trajectory of the target is predicted on the basis of a series of location measurements.
Abstract: A method and system for providing navigational data required to guide an air-to-air missile to a target. The missile is equipped either with an infrared seeking sensor or a radar system. The trajectory of the target is predicted on the basis of a series of location measurements. A flight path of the missile is predicted such that the missile will intercept the target. Based on the predicted missile flight path, signals corresponding to the required rotational angle of the missile's sensor or radar antenna are generated and supplied to the sensor or radar's rotation control unit to cause the missile to move along the predicted flight path.
TL;DR: In this article, a bus is launched from a launch station remote from a target with the bus missile carrying a plurality of sub-missiles, which are arranged to deploy ahead of the bus and are guided to the target under the control of a guidance beam generated in and transmitted from the bus.
Abstract: A missile system and a method of missile guidance in which a bus missile is launched from a launch station remote from a target with the bus missile carrying a plurality of sub-missiles. The sub-missiles are then launched from the bus missile during flight of the bus missile. The sub-missiles are arranged to deploy ahead of the bus missile and are guided to the target under the control of a guidance beam generated in and transmitted from the bus missile.
