Study On Antimissile-cooperation Problems For Exo-atmospheric Multiple Kill Vehicle

The Multiple Kill Vehicle program aims to intercept missile targets throughone or more Multiple Kill Vehicles dispensed from a single booster, MKV hasthe potential to solve many of the most difficult countermeasure challenges, liketarget-identification. In this paper, the target allocation strategy and terminalGuidance Law of MKV will be studied.First, the inceptor’s dynamic and kinematic model is established, thendesign a nominal trajectory, the simulation result of the inception scenecoincided the model, then the factors cause error between actual trajectory tonominal trajectory are studied.Based on the inception of MKV, targets allocation model is established, andthe qualitative determination of Threaten Degree of targets and Kill-Effectiveness Degree are analyzed. Use the genetic algorithm to solve thisproblem that has characteristics of fast convergence and good global searchcapability.At last, this paper focuses on the application of differential geometric (DG)guidance law. The DG guidance curvature and torsion commands are derivedthrough classical differential geometry theory. In order to applied this guidancelaw, the guidance commands are transformed to the time domain. To verify theperformance of this new guidance law, compare the simulation results of DG toanother guidance law-True Proportional Navigation (TPN). The DG can suppressthe rotation of the line of sight, especially to highly maneuverable target, the loadof which is also smaller the TPN during the end of inception,...
