| 摘 要： | 在研究卫星总体参数对TDICCD推扫成像调制传输函数MTF（Modula Transfer Function, MTF）影响关系的基础上,提出了一套模拟卫星在轨成像MTF下降的技术方法。通过这套模拟方法，建立了卫星总体参数与在轨成像质量MTF下降之间的关系，为用户根据对遥感图像质量MTF指标的需求来确立对卫星主要总体参数的要求提供了分析手段。 |

| Abstract: | More and more modern high resolution optical remote sensing satellites are being equipped with TDI CCD cameras. Modulation Transfer Function (MTF) is an authoritative means in evaluating the quality and implementation capability of the imaging system. For the purpose of evaluating the satellite criteria in the phase of production, it is necessary to simulate images with the satellite MTF criteria in enough reality. Based on a detailed analysis of the relationship between the satellite criteria and the on-orbit satellite TDI CCD imaging degeneration, this paper gives a method for the simulation of the degeneration process. With the method, a soft ware system was built to simulate the on-orbit imaging process of the designed satellite, which can provide the application experts with a powerful tool to judge the satellite in designing and production. |
