摘　　要：提出了一种新的基于虚拟图像注入的目标模拟器的研究方法。该方法基于速度追踪原理。模拟器从主控计算机获得跟踪设备及目标的参数,用DSP产生图像数据,FPGA控制图像时序,最后通过Camera Link接口将目标跟踪的图像数据发送出去,完成对目标捕获及跟踪的模拟训练过程。给出了软、硬件实现的方案和结构。跟踪捕获过程可以达到目标场景的全景性和实时性,能够满足光电跟瞄设备的运行维护与操作训练要求。A new research method of target-simulator based on virtual image injection is introduced, which is based on principles of velocity-tracking. Simulator accesses the parameters of tracking equipment and target from master computer. Image data are generated by DSP and image timing is controlled by FPGA. Finally, image data of goal tracking are sent through the interface of Camera Link and the simulation training process of goal capturing and tracking is completed. The software solutions and hardware architecture are given. The process of tracking capture achieves to panoramic and real time of target scene. It also can meet the maintenance and training request of the photoelectric tracking device.
