本文讨论SAR光学处理器电子控制与显示系统。这套系统中含有将张力误差控制在±10g以内的胶片张力控制,它是带有AGC的位置控制系统。确保数据输片机和图像输片机跟踪精度优于0.5％的胶片速度控制,它是由一台精密脉冲信号发生器控制的两套具有复合控制功能的锁相速度控制系统。线阵CCD成像器件与图像存贮器的有效组合,使SAR光学处理器具有快速图像显示能力。采用声光调制器(AOM)的光强稳定系统,可将激光器输出强度稳定在±2％以内。还有位置伺服式电动调焦以及附加信息的译码显示与记录等。
This article discusses the SAR optical processor electronic control and display system. The system includes film tension control that controls the tension error within ± 10g, which is a position control system with AGC. To ensure that the data gimbal and video gimbal tracking accuracy is better than 0.5% film speed control, which is controlled by a precision pulse generator with two sets of complex control of the phase-locked speed control system. The efficient combination of a linear CCD imaging device and image memory enables the SAR optical processor to have fast image display capabilities. With AOM light intensity stabilization system, the laser output stability can be stabilized within ± 2%. There position servo electric focus and additional information decoding display and recording.
