The Anti-ship Missile Seeker System Modeling And Simulation Research

Anti-ship missile seeker has developed rapidly in recent years,it can complete the accurate tracking and combat of sea targets,so the anti-ship missile seeker system modeling and performance simulation has very important significance by using computer simulation method.Based on the working principle of anti-ship missile seeker,this thesis builds a seeker simulation system,which can describe the whole process of seeker search tracking.After determining the system simulation workflow,the system framework and the model of each module according to the component modeling method has been established.Component modeling is the hierarchical division of the radar system,each layer to achieve different functions,each layer consists of different sub-components.The underlying component is a completely independent design and can be replaced by a small module,the internal software code has been packaged,only to provide the model input and output interface,the user does not need to know the component software implementation method,just know the input and output data stream,this is a logical package that hides the internal implementation principle,it was low coupling,reusable,and maintainable.The component model library covers the various functional components needed for radar system simulation,including transmitter,environment,receiver,signal processing,data processing,and servo control.The chaff signal modeling is completed in the environmental components,according to the chaff signal generation principle to generate the signal,and completes the signal time domain,frequency characteristics of the analysis,based to its target signal in the spectrum of the difference,the use of chaff signal spectrum characteristics of the wide anti-chaff interference processing,to simulate the more complex simulation scenarios for expanding the application of the seeker system.Then the simulation results obtained in different simulation scenarios are analyzed,and the performance indexes of the seeker system are analyzed,such as the measurement error and precision.Finally,the simulation control platform is given,which can realize the functions of inputting parameters in the interface,setting the simulation scene intuitively and displaying the track after the simulation is completed.The simulation system is built on the Visual Studio 2010 platform,and the model library is built by encapsulating the modules into the Win32 dynamic link library file,and the simulation control platform is set up to realize the visualization of the visual parameter setting and the tracking result.It is possible to test the effect of anti-jamming measures by analyzing the principle and time-frequency characteristics of chaff jamming signal,which can lay a foundation for the simulation of anti-ship missile seeker system in more complicated environment and has certain significance in engineering application.
