The solar irradiance monitor (SIM)  with the design accuracy of 5  used to monitor the secular changes of the total solar irradiance on FY-3 satellite  takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method  this method simplifies the structure and cuts the cost  but the measuring accuracy is affected by the sun-synchronous orbit  sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment  studies on the affection of different sunlight incidence angles to the measurement accuracy. First  by the satellite tool kit (STK) simulation software  simulates the orbital parameters of the sun-synchronous satellite  and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite  and base on the components designs the field of view and the installing angles of the SIM. Then  designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis  measures the total solar irradiance by the SIM at each angle  and compares to the irradiances of the SIAR reference radiometers  and gets the coefficient curves of the three channels of the SIM. Finally  by the quadratic fitting  gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302  R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance  and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.  
Non-uniformity correction in multi-CCD imaging system (EI CONFERENCE) 会议论文  OAI收割

The non-uniformity phenomenon exists in each channel of multi-CCD imaging systems. The factors which lead to the problem are complex. The conventional calibrating algorithms can not consider all of these factors and have poor effects. According to the characters of multi-CCD imaging systems  a non-uniformity correction method based on the scene was proposed by adopting the traditional two-point correction theories. The correction coefficient of each channel image can be calculated via the linear relation between the two neighboring pixel lines in the two-channel images. Compared with the conventional two-point calibration and multi-point calibration methods  contrastive calibrating results were obtained. This method does not need any standard lighted image as reference source  which provides a real time way for calibrating the multi-CCD imaging systems in practical applications. 2010 IEEE.
