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.

Three-Line CCD Camera is a multi-channel solid mapping camera. There are three signal channels in one camera
and twelve channels in three cameras for the three-line CCD camera. Because there is a little difference between different channels
the image grey of different camera channels is a little difference for the same region. Those differences include in two aspect: the difference between the cameras each other and the difference between different channels of the same camera. So they make a mistake when the images of different channels are matched. In the paper
the camera response curves have been described through ground radiation calibration to the multi-channel camera
furthermore
the channels calibration coefficients have been gotten based on making a certain the output basis channel. So the differences between different channels are reduced through radiation calibrating each channel
and the outputs of all channels are almost same
the accuracy of matching image is improved.
