摘要
为满足红外成像制导导引头的测试和半实物仿真试验,提出了一种高对比度红外面源目标模拟器方案。模拟器包括图像生成计算机、图像修正计算机和MOS电阻阵逻辑控制及驱动器,通过光纤构成分布式系统。图像生成计算机接收弹道仿真计算生成的弹目相对运动参数,生成红外场景图像,通过光纤网传送到图像修正计算机,对数据进行非线性、非均匀性修正,利用机内PCI图像数据传输驱动卡将数据传输到安装在转台上的MOS电阻阵逻辑控制及驱动器;该驱动器产生MOS电阻阵温度控制信号和的时序逻辑,驱动MOS电阻阵产生200Hz的红外图像。该方案已经在成像导引头测试中得到验证,导引头可清晰成像并稳定截获生成的红外目标。
For the test and hardware-in 4oop simulation of the infrared imaging guided seekers, an infrared targrt simulator with high contrast was designed. It was distributed based on fiber net, and included an image generation computer, an image correction computer and a MOS resistor array driving computer. The image generation computer received trajectory data of a missile simulator, generated IR images and transmitted these data to the image correction computer for non-linear and non-uniformity correction. After that, a PCI card inside the computer sent them to MOS the resistor array driving computer, which generated the logical control signals and grey control signals to drive MOS resistor array to output IR images at 200 Hz. The simulator has been testified by an imaging guided seeker, which can get distinct IR image and capture the IR target stably.
