Design And Development Of The Test System For Information Fusion System Of Multi-mode Composite Seeker

The multi-mode compound guidance is a hot research issue in the field of modern national defense and military.As the key technique of composite seeker,the scheme and algorithm of information fusion for compound guidance have been continuously developed and matured.At the same time,the interference technology for seekers is also in continuous evolution,and the background of interference for combined guidance weapons become more and more complex.So,how to simulate the complex battle environment in modern warfare and how to verify the performance of information fusion system become an urgent problem to be solved.Aim at this problem,a test system for information fusion system implemented on TMS320C6678 is designed and developed based on computer modeling simulation.Then,the performance,such as the precision of fusion,the capacity of anti-jamming,and real-time of the distributed information fusion scheme are intuitively and accurately verified through several sets of simulation experiments by the test system.Firstly,the distributed information fusion is introduced,and the key algorithmic theory,such as time-space registration,track association,target identification and track fusion involved in the scheme are expounded one by one according to the related literature.Then,the interference of radar/infrared/laser composite seeker is classified on fully researching the relevant literature,and the principle of several typical interference,such as RGPO,infrared decoys,laser angle deception jamming are deeply analyzed.Then the jamming's trace points is simulated.On this basis,the proportional navigation method is used as the seeker's guidance rate to simulate the missile's process of searching and tracking under the background with complex interference,and then the observation data at the front-end of seekers is generated for information fusion system to debug the algorithms.Next,the design requirements of the test system is analyzed,and the functional modules of the test system are divided in detail according to the design requirements.Then the class diagram and the case figures of the test system are designed according to the philosophy of UML.Based on this foundation,a test system for the information fusion system of multi-mode compound seeker is developed in Qt5.8.0 combined with the existing hardware.Then a series of software design methods such as file read/write,UDP communication,interactive interface,and graphic drawing are used to design and achieve the function of the test system,such as data generation,algorithm simulation,result display and performance evaluation in detail.And the runtime exceptions of the test system are also summarized and solved.Finally,the test system is used to carry out the distributed information fusion scheme by a series of simulations.And the results of the experiments show that the test system has the function of software debugging and performance verification for the information fusion scheme and related algorithms,and provides the simulation data and theoretical references for the application of information fusion technology.
