Using infrared target simulation technology, can simulate real objects close to the issue of infrared radiation plans for the infrared-guided weapons detectors to provide verification environment, infrared-guided weapons to shorten the development cycle and reduce development costs. The purpose of this dissertation is to develop infrared-guided missiles to semi-loop simulation of the infrared target simulator Resistance Array of the electronic control system.Based on this principle and sufficient analysis of IR imaging target simulator, the functional and technical requirement of control system is determined, and the overall scheme of the system is demonstrated.On the hardware design, according to infrared target simulation Resistance Array electronic control system of functional requirements, and the simulation image data sent cards, image-driven combination of control, infrared image data reception card portfolio and power development. This paper elaborated on the various functional units of the design, analysis of the various functional units of the design process, the design process and against the use of key technologies: LVDS technology, ping-pong storage technology, high-speed D/A technology, high-speed A/D technology, based on FPGA design of the control logic done a focus on.In software design, for high-speed image data transmission requirements, using WDM-driven development framework to achieve the simulation image data sent cards and infrared image data reception card for the DMA drivers.Finally, the analysis of the Resistance Array electronic control system of nonlinear correction methods, the corresponding technical solutions is given. In addition, given a specific method of debugging and debug the results. Commissioning results show that: The Development of the infrared target simulator Resistance Array electronic control system of the functional and technical indicators in line with the requirements of the development task.
