New Impact Time and Angle Guidance Strategy via Virtual Target Approach

“…Since Jeon first proposed the issue of ITCG, there have been many achievements in this field. [10][11][12][13][14][15] It should be pointed out that a suitable common impact time should be predesigned when aforementioned guidance laws are used to conduct a salvo attack of multiple missiles. However, it may not be easy to determine a suitable common impact time for multiple missiles.…”

The target-encirclement guidance problem for many-to-one missile-target engagement scenario is studied, where the missiles evenly distribute on a target-centered circle during the homing guidance. The proposed distributed target-encirclement guidance law can achieve simultaneous attack of multiple missiles in different line-of-sight directions. Firstly, the decentralization protocols of desired line-of-sight angles are constructed based on the information of neighboring missiles. Secondly, a biased proportional navigation guidance law that can arbitrarily designate the impact angle is cited. The missiles can achieve all-aspect attack on the target in an encirclement manner by combining the biased proportional navigation guidance law and dynamic virtual targets strategy. Thirdly, the consensus protocol of simultaneous attack is designed, which can guarantee that all missiles’ time-to-go estimates achieve consensus asymptotically, and the convergence of the closed-loop system is proved strictly via the Lyapunov stability theory. Finally, numerical simulation results demonstrate the performance and feasibility of the proposed distributed target-encirclement guidance law in different engagement situations.

“…In previous work, the multi-aircraft cooperative attack is mainly divided into two ways. One is individual homing [1][2][3], which can attack the target simultaneously by setting a unified impact time. Although individual homing can reach simultaneously attack, the problem of this method is that it is difficult to establish the attack time reasonably when the characteristics of the aircraft are inconsistent.…”

“…The cooperative guidance problem against maneuvering targets is more complicated than stationary targets. (2) In our paper, a cooperative guidance law is designed without using the target's acceleration information. In [32][33][34][35][36][37] the target's acceleration needed to be measured, which is probably unavailable in engineering practice.…”

The problem of impact angle constrained distributed cooperative guidance against maneuvering targets with undirected communication topologies is studied. A novel distributed cooperative guidance strategy is proposed to realize simultaneous attack with impact angle constraint. Firstly, the kinematic equations for the engagement are established. According to the engagement equations, the cooperative guidance problem is divided into two units, which include the cooperation of both impact time and impact angle. Secondly, the guidance algorithm is designed separately for simultaneous attack and dealing with the impact angle constraints. The problem is transformed into a consensus problem via disturbance compensation and feedback linearization technique. The convergence of the guidance algorithm is proven by using the consensus theory. Finally, numerical simulations are presented to verify the effectiveness of the proposed cooperative guidance law.
