Research On Key Technologies Of Multi-bomb Coordinated Attack Strategy

With the trend of future war towards informatization and intelligence,new intelligent ammunition represented by cruise missiles has received extensive attention from major military powers around the world.In cruise missile operations,a single cruise missile can no longer meet the needs of future informatized warfare.Multi-cruise missile coordinated attack operations can greatly improve breakthrough capability,electronic countermeasure capability,and overall combat effectiveness,making them more suitable for future complex warfare requirements.This paper focuses on the study of multi-missile coordinated attack operations and conducts in-depth research on target threat assessment,target allocation,and key technologies of coordinated guidance.The main research contents are as follows:(1)Based on the research purpose of this paper,the operational system,process,and strategy of multiple missile cooperative attack are analyzed.Operational space models,cruise missile cluster models,and target distribution models are established.Some relevant theoretical knowledge of cooperative guidance is introduced to lay the foundation for subsequent research.(2)In response to the problem of cooperative attack target threat evaluation,a threat evaluation method using intuitive fuzzy TOPSIS and fusion variable weight VIKOR is proposed.Static and dynamic properties of attack targets are comprehensively considered,and their indicators are selected and quantified.By constructing an intuitive fuzzy TOPSIS model and a fusion variable weight VIKOR model,the static and dynamic threat levels are calculated to obtain the composite threat level.Reasonable target comprehensive threat evaluation coefficient is obtained to provide effective data support for subsequent cooperative attack target allocation research.(3)In response to the problem of cooperative attack target allocation,a target allocation model is established under multiple constraint conditions.The DE algorithm is improved by guiding "exploratory" population cooperation evolution,adaptive selection mutation rate,mutation strategy,and crossover rate,and the improved algorithm is applied to the established model to solve the optimal solution of target allocation.Simulation results show that the improved algorithm can improve global optimization ability and convergence performance,and can find the optimal target allocation scheme more quickly and effectively,proving the feasibility and effectiveness of the algorithm.(4)Based on the optimal target allocation scheme,research on three-dimensional cooperative guidance problems is conducted,and two cooperative guidance laws are designed.One is the three-dimensional cooperative guidance law under attack angle constraint,which controls the attack angle through adaptive sliding mode guidance law,and conducts simulation comparison experiments with augmented proportional guidance law.Simulation results show that the guidance law can meet the requirements of attack angle constraints and has high guidance accuracy,proving its effectiveness and superiority.The other is the three-dimensional cooperative guidance law under attack time constraint,which adjusts the attack time of the cruise missile through maneuvering control on the heading channel to make it approach the specified value.On the pitch channel,adaptive sliding mode guidance command and augmented proportional guidance command are used respectively,and simulation comparison experiments are conducted.Simulation results show that the guidance law can meet the requirements of attack time constraint and guidance accuracy,proving its effectiveness.
