Abstract

This paper proposes a novel three-dimensional guidance method based on clock synchronization algorithms, creatively solving the problems of randomized change, non-connection and even communication outage caused by packet loss and delay in the co-guidance of loitering munitions. The proposed method is characterized by fast convergence of the aspect angle rate in the longitudinal plane, and the attack time constrains in the lateral plane. Normal accelerations on the two sub-planes are thereby calculated, so as to control the munitions’ co-attack. Simulation experiments show that the proposed method can ensure reliable and stable asymptotic agreement of attack time expectation for the cooperative multiple munitions under the switching and noisy networks.

Highlights

Loitering munition is a kind of new concept munition which can perform “cruising flight” and “standby” above the target area and perform a variety of operational missions
Simultaneous arrival is a key issue in the study of coordinated attack of multiple loitering munitions, which can be attributed to the consistency of guidance time [4]
This paper mainly studies the problem of time consistency cooperative guidance of loitering munition for ground fixed targets in three-dimensional space

Summary

Introduction

Loitering munition is a kind of new concept munition which can perform “cruising flight” and “standby” above the target area and perform a variety of operational missions. The consistency problem of guidance time mainly studies the information interaction mode between each munition in the coordinated attack system, so that the guidance time of all munitions tends to the same value, so as to achieve the maximum damage efficiency to the target. Jeon et al proposed a homing guidance law called cooperative proportional guidance (CPN) for several for one participation scenario of typical anti-ship missile. This method has the flexibility to allow different speeds to cooperate and attack simultaneously [5]. Kumar et al proposed an impact time guidance law based on sliding mode control. In the literature [8], in order to consider the multiple constraints and time-variant velocity basically effectively, two closed-loop cooperative guidance methods are developed, by employing the efficient convex optimization technique and receding horizon control (RHC) strategy
