Studies on Multi-Constraints Cooperative Guidance Method Based on Distributed MPC for Multi-Missiles

Cooperative terminal guidance with impact angle constraint is a key technology to achieve a saturation attack and improve combat effectiveness. The present study envisaged cooperative terminal guidance with impact angle constraint for multiple missiles. In this pursuit, initially, the three-dimensional cooperative terminal guidance law with multiple constraints was studied. The impact time cooperative strategy of virtual leader missile and follower missiles was designed by introducing virtual leader missiles. Subsequently, based on the distributed model prediction control combined with the particle swarm optimization algorithm, a cooperative terminal guidance algorithm was designed for multiple missiles with impact angle constraint that met the guidance accuracy. Finally, the effectiveness of the algorithm was verified using simulation experiments.

Fixed-time cooperative guidance for multiple missiles with impact angle constraint

For the guidance problem of multiple missiles attacking a maneuvering target simultaneously in plane, a novel fixed-time distributed cooperative guidance law with impact angle constraint is designed in this paper. The design process of distributed cooperative guidance law can be roughly divided into two parts. First, based on the nonsingular terminal sliding mode control, a cooperative guidance law on the line-of-sight (LOS) direction is developed, which can guarantee that all missiles hit the maneuvering target simultaneously. Second, another guidance law in normal direction of the LOS direction is designed to achieve the fixed-time convergence of LOS angular rate and LOS angle. Finally, numerical simulations verify the effectiveness of the proposed cooperative guidance law for different engagement scenarios.

Aab Ky Marr! Pulwama to Balakot: India's New Normal

Pulwama/Balakot crisis is important for several reasons. The prime amongst it is that Pakistan changed the rule of the game. It not only thwarted India's design, it effectively demonstrated that it could respond to any Indian aggression through conventional means. The paper argues that although India and Pakistan had a narrow escape during the conflict, there is a need for a cautious approach when it comes to Indo-Pakistan strategic stability. The papers focus on the crisis behavior of both countries and argue that while India intentionally initiated the crisis whereas Pakistan took every step to deescalate. At the end of the crisis, Modi claimed that India was prepared to hit Pakistan with multiple missiles if it had not returned the IAF pilot. While it might be music to his ultra-Hindu fundamentalist supporters, in fact, it was nothing but a desperate attempt to restore his credibility. In the subcontinental culture, aab ky Marr explains such a mindset.
