| The trend of modern war information is becoming increasingly obvious.As an essential means of precision target attack,precision guided weapons have gradually replaced the original combat weapons and become the dominant battlefield.Multi-mode composite guidance is the core guidance mode of precision guided weapons,and the information fusion algorithm is the soul algorithm of multimode composite guidance.Therefore,information fusion algorithm is widely used and researched in the field of precision guidance.Since the information fusion algorithm needs to verify the correctness and real-time of the algorithm before it is put into use;for the correctness of the algorithm,it is necessary to evaluate the algorithm reasonably according to the actual application background.For the real-time performance of the algorithm,pure digital simulation can’t verify the running speed of the algorithm on the hardware platform.At present,the information fusion algorithm lacks of system 1.Verification platform.In view of the above problems,this paper designs and develops the simulation test system of multi-mode composite guidance information fusion.The simulation and test system of multi-mode composite guidance information fusion introduced in this paper is a general semi physical system,which can verify the reliability and real-time performance of information fusion algorithm in different background.At this time,the system can simulate and model the observation data of space-based,space-based,ground and missile platform,simulate multiple battlefield environment,and realize the diversity of observation data;meanwhile,the system can set different environmental variables and simulate related interference to verify whether the information fusion algorithm under different application background is reasonable.The test system is universal.The multi-platform and multi-sensor measurement data are obtained by the upper computer simulation software,and the information fusion algorithm is stored in the information fusion processing board of the hardware platform.Through the interaction between the software and hardware platform,the correctness and real-time performance of the information fusion algorithm are verified more accurately.This paper introduces the architecture and basic algorithm of information fusion algorithm,then introduces the modeling and simulation method of multi-platform multi-sensor measurement data in detail.The modeling and simulation work of multi-platform multisensor measurement data and related interference under the background of sea,air and ground are carried out by MATLAB software.Then,the multi-mode composite guidance information is introduced.The framework and software and hardware of the simulation test system are integrated.The structure of hardware platform is given.The data transmission is simulated by ADALM-PLUTO RF transceiver,and the information fusion algorithm is realized by tms320c6678 signal processor.The method of building the software platform of the upper computer is also given.Then,according to the construction method of the software platform,the UML software development technology will be used to develop the software.The software platform is divided into several modules.Under the Qt development environment,it is implemented by C++ language one by one.Through the mature information fusion technology in the laboratory,the test system can verify the information fusion algorithm correctly.Finally the results show that the data simulated by the upper computer software platform can be used to verify the information fusion algorithm.The multi-mode composite guidance information fusion simulation test system developed in this paper can be used for the information fusion algorithm test. |
