Space Radiation Effect on Photoelectric Signal Processing System of Optical Remote Sensor

Aiming at the photoelectric signal processing system of optical remote sensor, this paper described the way to study the space radiation effect. Firstly, the space radiation environment of the regular orbits for remote sensor was introduced. Based on the photoelectric signal processing system of optical remote sensor, the circuit component and the main devices of this system were showed. Then, the main concern of this paper was to analyze the hazards of the space ra- diation effect by the following grades, from the device, circuit unit, to circuit system. According to the radiation - resis- tant ability of the devices, the opinion about weak points in the space radiation effect and the irradiation test of the main devices were proposed. Lastly, the research method and procedure for the space radiation effect were summarized.
