摘　　要：基于MOS电阻阵的红外场景模拟器是半实物仿真系统中的关键设备。介绍了256×256元MOS电阻阵的结构和工作原理,研究了其驱动方法,详细介绍了驱动系统中图像数据传输电路和驱动控制逻辑电路的设计。驱动系统与电阻阵的联合实测结果表明:驱动系统的图像刷新频率达231.4帧/秒,单元像素灰度分辨率为16 bit。经实际使用,该驱动方法完全满足红外成像制导武器测试和半实物仿真的使用需求。Dynamic infrared scene projector based on MOS resistor array is the key equipment for the hardware-in-the-loop （HWIL） simulation system. The structure and working principle of 256 × 256 MOS resistor array is introduced. The drive method is researched, and the image data transmission circuit and drive control logical circuit are described. The drive system and resistor array are tested together and the experiment result shows that the image refresh frequency reaches 213.4 frames per second and the each pixel grayscale resolution is up to 16 bits. The practical application indicates that this drive method per- fectly meets the requirement of testing and HWIL simulation of infrared imaging guidance system.
