Coordination technology of ranging-imaging guidance integrated fusing and aimable warhead

In order to achieve enhanced lethality by implementing the aimable warhead, the aiming direction of the warhead was parameterized in missile coordinate system，and the missile-target terminal encounter parameters were derived with space analytic geometry method based on IR-imaging guidance and laser-ranging integrated fusing technology. According to the two encounter concepts of the aimable warhead side-attack target and forward-intercept target at endgame, the coordination models of fuse and aimable warhead were studied separately in detail, so that the aimable warhead system could aim at target and detonate the warhead after the optimum time delay to place fragments on the target during endgame. Simulation results show that IR-imaging guidance and laser-ranging integrated fusing is able to provide the required information to the aimable warhead, so the two models are valuable reference for the design of ranging-imaging guidance integrated fusing and the engineering application of the aimable warhead.
