摘要	In order to increase the dynamic range of push-broom remote sensing cameras, we investigate the special setup of TDI stages of panchromatic and multispectral bands and study the interpolation method and the image fusion method of according images. Firstly, parameters, including common pixel size and bands of TDI CCD image sensors, and the present methods for obtaining high-resolution fused images are introduced. The traditional strategies for TDI stages' setup are analyzed. Secondly, raw data for high dynamic range(HDR) images are obtained by increasing the value of the panchromatic band's TDI stages and decreasing the value of multispectral band's TDI stages. Finally, the unique fusion and interpolation algorithm is proposed and high-dynamic-range and high-resolution gray images can be obtained. The calculation and experimental results indicate that this method can effectively improve the dynamic range of push-broom cameras. Meanwhile, the dynamic range of final fusion images can be improved by 18.06 dB when the TDI stages of the panchromatic band are multiplied by 2 and the TDI stages of multispectral bands are decreased by 1/4. The method proposed in this paper can successfully extend the dynamic range of push-broom remote sensing cameras. 2019, China Science Publishing & Media LTD. All right reserved.
