线阵CCD航空遥感模拟器的研究

Study on a Kind of Linear CCD Simulator

为克服线阵CCD航空遥感器研制周期较长、无法进行前期系统联调工作的困难,设计了一种基于VC界面与现场可编程器件FPGA的线阵CCD航空遥感模拟器。整个系统通过VC仿真界面作为人机操作平台,完成指令、信息的交互;以FPGA作为模拟线阵CCD相机的核心器件,根据相应的指令和行同步信号、帧同步信号,按照线阵CCD相机的输出时序要求输出图像数据。模拟器的设计缩短了项目研制周期,为后期的联试和图像采集存储等工作提供了保证。

To overcome the difficulty of long development period and incapable of online adjustment for the linear CCD aerial remote sensor,a sort of simulator based on the VC interfaces to the programmable component of the FPGA was designed.Through the VC simulation interface for the man-machine operating platform,the whole system completed the instruction and interaction with the linear CCD.As a core element of the camera,FPGA which accorded to the instructions,linear signals and frame signals,output the image data in accordance with the timing of the linear CCD camera.The design of the simulator shortens the project period and provides guarantee for the trial and image gathering.
