【Abstract】 TDI-CCD Subpixel dynamic imaging technology was a valid novel approach for meeting the requirements of high-resolution and lightweight of remote sensing cameras. Because of its special work method, the affect of velocity mismatch and misalignment was unavoidable.Through analyzing the effect on MTF, the result shows that it is very important to improve quality of imaging through improving the synchronous accuracy and reducing the drift angle.更多还原
