摘要
目标模拟系统作为导引头电气系统半实物仿真实验的重要组成部分,向可见光探测系统提供动态目标和场景图像,以测试其发现、探测和跟踪目标的能力。分析设计了可见光目标模拟系统结构以及构建了DMD驱动控制模块和光学系统平台,实现解决了DMD驱动控制、灰度调制以及光学投影等关键问题,并成功地实现了将仿真计算机中仿真图像通过DVI接口传输到DMD上以60Hz频率显示。最后,与探测设备进行对接,对可见光目标模拟系统的所有功能进行了验证,结果满足仿真实验要求。
As an important part of the hardware--in--the--loop simulation experiments in the electrical system of the seeker, the target simulation system provide dynamic target and scene images to the visible light detection system to test its ability to discover, detect and track the target. The architecture of a visible target simulation system is analyzed and designed, and the entire system platform is built. After hav- ing： solved the key issues of the DMD drive and control, gray--scale modulation and optical projection, simulation image from simulation com- pwler is successfully displayed on DMD through DVI interface at the frequency of 60 Hz. And when visible light target simulation system is interconnected with detected device, all the features are verified on system platform and the results meet the simulation experiment require- ments.
