Imaging Monitoring and Measurement of Moving Target in Orbit Based on CMOS Image Sensor

摘要

In recent years, the number of spacecraft launches has showed explosive growth, the types of satellites have become more and more abundant, and the execution of moving target in orbit has become more complex, the traditional telemetry method has not been able to meet the new requirements, and the visual telemetry has become more demanding. Usually, the execution of in-orbit moving target is short-term and one-time, which is executed immediately after entering orbit. The monitoring requirements of the actuator are short term, with a life span ranging from a few minutes to a few hours. The monitoring camera based on CMOS image sensor is small in size, low in weight, low in power consumption and low in satellite resource consumption, which is just suitable for the monitoring needs of the moving target in orbit. In this paper, the in-orbit target monitoring requirements of CMOS monitoring camera are analyzed, camera parameters are designed, and the application is summarized.
