Research On Early Warning Radar Supporting GBI Anti-Missile Engagement Evaluation Algorithm

Based on the relevant test data,this study selects the evaluation of the anti-missile engagement algorithm of the ground-based mid-course anti-missile weapon(GBI)under the early warning radar support as the research goal,focusing on the long-range launch and long-range interception modes of the early warning information to support the interception weapon operation.The research proposes analysis and evaluation indicators,and establishes an efficacy analysis and evaluation algorithm.Finally,use the "situation simulation environment" built in the research group to verify the algorithm and complete the graduate thesis.The main work accomplished in this paper are:On the one hand,based on the dynamic equation of the interceptor and relevant tests,a multi-stage motion model that can simulate the ground-based interceptor(GBI)is established,and through the test,it can basically meet the needs of the current simulation test.First,the classification,motion law,motion characteristics and basic motion model of ballistic missiles are studied,and the basic principles,rules and guidance methods of GBI are further studied,digested and understood,so that the established motion model conforms to the basic motion law.It lays the foundation for further research on the early warning process and the establishment of the interception model.Secondly,focus on the analysis and research of GBI,establish and complete the motion model modeling of the interceptor according to the subject background and the technical parameters and key indicators of the GBI dynamic model,and realize the motion model of multi-stage launch and terminal guidance.Calculate its motion characteristics,and give the motion height and time relationship.On the other hand,according to the established interceptor motion model,a GBI anti-missile engagement evaluation model supported by early warning information is established,and the integrated verification is carried out in combination with the simulation test.First of all,to meet the needs of the current simulation test,focus on the external characteristics,that is,the interception height,time,speed and other aspects are basically consistent with the long-range interception motion law,which is used to reversely calculate the timing of the early warning guarantee time,including Evaluation indicators and evaluation algorithms support analysis and research on the relationship between early warning and interception timing,as well as the requirements for farthest interception,secondary interception,and launch window.Secondly,according to the established interceptor projectile motion model,the sequence requirements for the early warning guarantee time are deduced,and the algorithm of how to determine the interception point is given when the early warning sequence is given.Finally,using the situational simulation environment built in the research group to simulate and analyze the gain effect of early warning information on supporting the GBI interception operation sequence.
