Abstract

We proposed a design method of infrared video processor, hereinafter referred to as processor, used on geostationary orbit (GEO), for the performance of detector degraded after long time working in the complex space environment. Compared with the traditional design, this method used on-obit calibration technology to update the image preprocessing algorithm parameters and defective pixels. It improved single event effect (SEE) ability and implemented updatable function for the program of main controller, by used on-obit dynamic refresh and injection technology. The experimental results show that, the image quality kept stable when the performance of detector degraded. And the imaging system worked normally, and no need to reload the program of main controller when SEE occurs. It can also update and load the program of main controller with bus instruction. This method ensures the processor working normally in harsh space environment, and provides technical expertise for the follow-up design of processor.
