IR target simulation and generation system based on MOS resistor array

For the test and hardware-in-loop 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.
