摘要
影响遥感相机成像质量的因素很多,为了提高遥感相机电子学成像质量,对核心元器件的信噪比、电路带宽、抑制高频信号干扰和暗电平箝位等影响因素进行了分析,提出了改进方法,并进行了实验验证。达到空间实际应用的要求。
There are lots of factors to affect the image quality of the remote sensing camera. In order to improve the elec- tronics imaging quality in remote sensing cameras, the signal noise ratio of core components, the bandwidth of the circuit, suppression of high frequency interference and black level clamping are analyzed in detail and the improvement scheme is pro- posed and tested. The test results show that the improvement method can satisfy the application requirements.
