In order to improve the attack effect from the top of maneuver target for air-to-ground missile, three-dimensional proportional navigation model with over-gravity compensation is established based on the relative motion equations. Three-dimensional ballistic trajectory of the missile attacking target is simulated based on the guidance and control closed-loop circuit. The effect of the over-gravity...
Aim at the fuzziness and grey characteristics of evaluation index information of not fully navigable route, this paper establishes navigation condition evaluation model that based on the grey-cloud whitening-weight function clustering theory. Based on the case study of evaluating Northeast Passage navigation condition, the result shows the Northeast Passage navigation condition is in the “unsafe navigation”...
Cooperative guidance for multiple flight vehicles against single moving target is studied in this paper. Two finite-time consensus protocols are developed for multi-agent system with input saturation which underlay the design of cooperative guidance law. The cooperative guidance approaches are investigated to solve the many-to-one interception problem, where two novel guidance laws considering the...
For the fast and accurate self-localization of mobile robots in navigation, artificial landmarks can be used very efficiently in the complex workspace. In this paper, in order to provide feedback and verification mechanisms in navigation technique, we design two types of artificial landmarks with symmetric rectangles and seven-part numbers, which show cross- ratio invariant under projective transformation...
