Abstract. The CCD detector is the core device of the space remote sensing camera. The performance of CCD detector greatly affects the performance of the whole remote sensing camera. The temperature of the CCD detector has a significant influence on its performance. In order to better study this influence relationship, the temperature impact verification of remote sensing camera detector was carried out. The test scheme of dark signal under high temperature environment and the test scheme of radiation calibration under different temperature conditions are developed. And the test verification was completed. Based on the analysis of the experimental data,the quantization relationship of the influence of temperature on the parameters such as dark signal, dark noise, dynamic range, noise and signal-to-noise ratio is obtained. These results have certain reference value for the development of space remote sensing camera.
