Abstract

The invention relates to a test system for impact analysis of imaging quality of TDICCD (Time Delayed Integration Charge Coupled Device) by multi-source interference, which can be divided into an error source interference and an equivalent sub system thereof, a TDICCD imaging sub system, an optical target, gesture error and an interference measuring sub system thereof, a signal collecting and processing sub system, and a wireless communication and ground comprehensive processing sub system. The error source interference and the equivalent sub system thereof is used to simulate interference generated by a solar sailboard / a control torque gyro system (CMGs) and a satellite platform in a spatial environment for the satellite. The measuring sub system is used to measure the gesture angle of the satellite platform and the vibrating linear velocity. The signal collecting and processing sub system collects sensor information and processes and analyzes and calculates the information correspondingly. According to the invention, main interference by motion errors of the satellite to the imaging quality of the TDICCD is simulated in the spatial environment on the ground, and the impact analysis of the imaging quality of the TDICCD by the multi-source interference is realized by combining a floating turntable for dynamical test and analysis of satellite gesture.

Description

technical field

[0001] The invention relates to an analysis and testing system for the influence of multi-source interference on TDICCD (Time Delayed Integration Charge Coupled Device) imaging quality, which is suitable for simulating the multi-source interference caused by agile mobile satellites with maglev CMGs as actuators on TDICCD remote sensing imaging. Background technique

[0002] In the 21st century, due to the traction of space science tasks, the improvement of mobile satellite capabilities and the rapid development of remote sensing loads, it is possible to use a single TDICCD camera strapdown installed on an agile mobile satellite for large-width, high-precision multi-level stereoscopic imaging. However, due to TDICCD's requirements on platform stability and the influence of complex space dynamics experienced by satellites in orbit, high-resolution observations based on TDICCD are facing great challenges. At present, some camera companies use small gyroscopes to...
