Problems solved by technology

Procedural maneuvering is highly practical and has little impact on the accuracy of the landing point, but the penetration probability is low; the optimal maneuvering maneuver has a high penetration probability, but it is easy to cause large deviations in the landing point

Embodiment example

[0371] In order to test the effect of the proposed maneuvering strategy, a numerical simulation is carried out for the case of a cruise missile attacking a surface target. The cruise missile attacks the surface target, and the surface target launches a defensive projectile to intercept the cruise missile. The guidance law adopted by the defensive projectile is PN, and the effective navigation ratio is 3. In this case, the cruise missile corresponds to the missile described in the present invention, the letter is M, the surface target corresponds to the target described in the present invention, the letter is T, and the defensive missile corresponds to the letter D.

[0372] When the above is pushed to the method of the present invention, it is assumed that the engagement models can be linearized along their corresponding initial collision triangles. In order to be closer to the actual combat situation in the simulation, the combat model used is a two-dimensional nonlinear mode...

Abstract

A differential game anti-interception maneuver penetration / precise striking guide method includes the following three steps of firstly, carrying out modeling of a three-body differential game model, wherein a warring three-party dynamics link model, a warring three-party linearized warring model and a three-body differential game model are included; secondly, carrying out dimension reduction processing on an original three-body differential game model and obtaining the new three-body differential game model; and thirdly, solving the new three-body differential game model based on the optimal control theory and obtaining the optimal control law of a guided missile, wherein solving of the Hamiltonian function of the new three-body differential game model and the optimal control problem corresponding to the new three-body differential game model is included. By means of the three steps, the establishing process of the three-body differential game model, the conversion process of the new model and the old model and the solving process of the differential game model are described, and finally, the differential game anti-interception maneuver penetration / precise striking guide method is obtained.

Description

technical field [0001] The invention provides a differential countermeasure anti-interception maneuver penetration / precise strike guidance method, which relates to differential countermeasure anti-interception maneuver penetration and landing precision control, and belongs to the field of aerospace technology and weapon technology Background technique [0002] With the development of modern guidance laws and anti-missile systems, the survival environment of missiles is deteriorating. Mobile penetration is an important means to improve the survival probability of missiles, so it is necessary to conduct in-depth research. [0003] Nowadays, there are two main types of maneuver penetration methods for missiles that have been studied more: procedural maneuver and optimal maneuver (the optimal maneuver is based on the assumption that the interceptor adopts the proportional guidance law (PN is directly used to represent the proportional guidance law). , with the aim of maximizing ...
