Example Embodiment

[0068] The drawings constituting a part of the present invention are used to provide a further understanding of the present invention, and illustrative embodiments and their description thereof will be described in the present invention and is not constituting the present invention.

[0069] like figure 1 The present embodiment provides a proactive defense guidance method for a three-body counterfeit strategy based on a differential game, in particular:

[0070] Step 1, establish a two-dimensional plane offensive missile - target - defense missile relative exercise equation:

[0071] like figure 2 As shown, considering the offensive missile, the target and defense missiles, the first-order automatic driver system, defines M, T and D represent offensive missiles, targets, and defense missiles, respectively. V M , V T And v D The speed of the offensive missile, target and defense missile is indicated, and its speed is constant; α, β and γ indicate the head of the offensive missile, ...

Abstract

The invention discloses an active defense guidance method of a three-body confrontation strategy based on differential game, and the method specifically comprises the following steps of: establishing a three-body confrontation differential game guidance kinematics equation; establishing an active defense guidance system with a feedback form in an active defense scene based on the established three-body confrontation differential game guidance kinematics equation, wherein the input of the active defense guidance system comprises feedforward control and feedback optimal control; the active defense guidance system controls a target missile not to be hit by an attack missile and controls a defense missile to effectively intercept the attack missile. According to the method, a nonlinear missile model is adopted for research, and the characteristics of high coupling, complex nonlinearity and the like of the missile are fully considered. The designed differential game guidance law better meets the requirements of practical application.

Description

technical field [0001] The invention belongs to the field of aircraft guidance method research. Background technique [0002] With the development of aerospace technology. At present, all kinds of highly maneuverable, intelligent, and high-speed missiles (such as high-speed cruise missiles, ballistic missiles, etc.) are constantly emerging. This kind of modern interception and offensive missiles integrating advanced technology is very effective against high-value air targets (missiles or aircraft, etc.) pose a significant threat. In such scenarios, due to the faster flight speed and high maneuverability of the intercepting missile, the target in the mission is often intercepted by the intercepting missile, resulting in mission failure. Therefore, in order to make the target aircraft successfully penetrate the defense, the three-body confrontation active defense scenario in which the target carries defense missiles can be used. Use defensive missiles to intercept offensive...
