In order to enhance the resolution of Charge Coupled Device (CCD) pixel with the pixel dimension and focal length of optical system unchanged
the problem of CCD geometric superresolution is educed. The problem is discussed in terms of software and hardware. In software
the bicubic interpolation is introduced
while in hardware
the subpixel imaging method is utilized. The subpixel imaging method integrates two uniform linear CCDs staggered by half dimension of pixel in one device. In operation
the line frequency is doubled. At last
the collected data is interweaved to synthesize a high resolution image. The two methods
bicubic interpolation and subpixel imaging
are simulated with Matlab7.0.1. The qualitative and quantitative analyses are given. The simulated results of lanczos and cubic spline interpolation methods are given simultaneously to show the performance of interpolation. The simulation result shows that the result images quality becomes better in both methods
but compared with bicubic interpolation method
the synthesized image PSNR gained from sub-pixel imaging is averagely enhanced by 2.1682dB
while the elapsed time is reduced to be about one forth. The subpixel imaging method could significantly mitigate the image blur introduced by undersample. 2009 IEEE.

In order to obtain three-dimensional observation effect with single satellite borne time delay and integrate charge coupled device (TDI-CCD)
pitching imaging is required. More accurate real-time image motion velocity vector computational model of space camera is also necessary to make the imaging perfect. Imaging motion velocity vector computation model must be set up on image plane at pitching imaging. According to the geometric relationship between the pitching imaging space camera and the Earth's rotation motion
satellite borne TDI CCD pitching imaging motion velocity vector model is derived by mapping the ground speed to the image plane and using coordinate transformation method. The numerical simulation results show that the image velocity model can reduce deviation angle error about 33' and about 30% image motion speed error compared to traditional ground velocity model. 2009 IEEE.

The radiometric calibration of the Time delay and integration Charge-coupled Device (TDI CCD) imaging system is a necessary part in the manufacturing TDI CCD camera. The radiometric calibration of the TDI CCD remote sensing camera is done in the State Key Laboratory of Applied Optics. The integration sphere is used for simulating different radiance
which is decided by the different sun vertex angle and different reflectivity of the ground. The parameters of the gain and stage of the TDI CCD remote sensing camera are given through the analyzing of outcome of the experiment. The outcomes are used in the practice and the errors are discussed in the end of the experiments.
