| 摘 要： | 针对某高分辨率空间遥感相机电荷耦合器件（Charge-Coupled Device,CCD）体积小、功耗大但温度稳定性要求高的特点,提出了通过相机发送指令控制补偿加热回路通、断电对CCD器件进行温度控制的方法,并利用IDEAS-TMG软件进行了仿真分析,分别给出了无补偿功率、补偿功率为10W、12.5W、15W与17.5W这5种情况下CCD器件的温度变化曲线。仿真分析结果表明：补偿功率为12.5W时CCD器件的温度波动最小,热设计结果满足各项温度指标。为了验证热设计的可靠性,焦面组件参加了整机的热平衡试验,得到了满意的结果。该设计方法对各类空间遥感相机高温度稳定性要求的CCD器件的热设计和热分析有一定的指导和借鉴作用。

| Abstract: | The characteristics of Charge-Coupled Device （ CCD ） in high resolution space remote sensing camera are small volume, high heat productivity but limited temperature fluctuation. In this paper, a new method is proposed to control the CCD＇s temperature fluctuation, which means the camera sends instruction to control thermal compensating circuit. The CCDs are simulated with the software IDEAS-TMG and five results are presented： no compensative power, 10W, 12.5W, 15W and 17.5W compensative power. Through the camera thermal balance test, thermal control effect of this method has been verified. The analysis method could give some guidance and reference for other space remote sensing camera CCD thermal control. |
