Differential Countermeasures Anti-Interception Maneuver Penetration/Precision Strike Guidance Method with Fall Angle Constraint

Abstract

A differential countermeasure anti-interception maneuver penetration / precise strike guidance method with fall angle constraints, which includes the following three steps: 1. Three-body differential countermeasure model modeling; including the dynamics model of the three parties at war, and the linearization of the three parties at war Engagement model, three-body differential game model; second, the original three-body differential game model is reduced in dimensionality to obtain a new three-body differential game model; third, based on optimal control theory, the new three-body differential game model is obtained to obtain the missile’s optimal Control law; through the above steps, the differential countermeasure anti-interception maneuver penetration / precise attack guidance method with the drop angle constraint can be obtained; the present invention has very concise expressions, and the physical meanings of its items are clear and definite; its penetration misses the target The quantity is large, the drop point accuracy is high, and the drop angle constraint can be satisfied at the same time.

Description

technical field [0001] The invention provides a differential countermeasure anti-interception maneuver penetration / precise strike guidance method with a fall angle constraint, which relates to a differential countermeasure anti-interception maneuver penetration, fall point precision control and fall angle constraint 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 represe...

AI Technical Summary

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
