摘　　要：在光电跟踪系统中,电视或红外热像仪视频信号由于长线传输引起的信号衰减和噪声增加给信号检测带来了很大影响。介绍了利用视频信号调理器MAX7452实现视频自动增益控制(AGC)的具体应用,可提高视频信号长线传输的保真度,减小衰减和噪声,使视频调理稳定。In an electro-optical tracker system, the signal detection of video from TV or infrared thermal imager are affected much due to signal attenuation and noises caused by long-wire transmission. The application of video AGC control through video conditioner MAX7452 circuit is presented, which improves the long-wire transmission fidelity of video signal and reduces attenuation and noise to keep video conditioning stable.
