Abstract


Infrared Imaging Seeker is an intelligent seeker extended source information processing method, self-identify complex target in complex background conditions, but also to target vulnerable parts selection, namely the hit point selection. Infrared imaging guidance technology for missiles to provide more objective information to better suppress background interference and improve the identification probability and hit accuracy. Subject design, playing on the computer simulation system is to provide a platform for the testing and analysis of the infrared imaging seeker, simulated bombs on the information exchange between the computer and seeker seeker's self-test, and by computer simulation system, missile seeker issue workflow control command, monitoring seeker status and system status, display a variety of information transmitted by the seeker and stored as data files for post-experimental impact evaluation. The paper introduces the basis of the research: the system functions and the design requirements, discusses the idea of ??the overall design of the simulation system, proposed the framework of the system structure, divided into various functional modules, from the development of dedicated PCI board design, FPGA functional modules, PCI device driver and the man-machine interface to write three aspects to start on. In the hardware design part describes the development of a dedicated PCI board design based on FPGA high-speed synchronous serial transceiver link and switch the amount of information input and output modules. About the PCI bus specification and works to introduce the structural features of PLX9056 chip functions to describe the mechanism of industrial control computer bus interface, and accordingly design a dedicated PCI board. HDLC protocol, byte the parallel CRC checksum algorithm, the Top-Down design method described FPGA function module design, selection of Xilinx FPGA chip XC2S300E achieve, using VHDL language to describe theoretically verified in Xilinx's ISE development tools integrated application, Modelsim completed the simulation of all functional modules and realized on FPGA. In the part of software design, to discuss the objectives of the PCI driver characteristics and driver use the WinDriver write special PCI card drivers running on the Windows operating system, the development of the bomb on the computer simulation system, hardware platform, using Visual C the preparation of the man-machine interface, information interactive computer simulation system with infrared imaging guidance seeker missile. Through hardware and software co-design, playing on the computer simulation system design through debugging.
