摘　　要：凭借对数变换、信号压缩、瞬时处理的功能和特点,对数视频放大器在雷达、电子对抗、声纳系统中得到了较多应用。由于专业性强、应用面窄、资料匮乏,因而在工程使用中存在认识模糊的情况。从解析概念入手,重点分析了对数视频放大器主要技术参数,最后给出了选择对数视频放大器的原则和方法。In view of the function of logarithmic transformation,signal compressing and instantaneous processing,the logarithmic video amplifier has a wide application in the fields of radar,ECM and sonar and so on. Because of the strong professionalism,the narrow application,the lack of reference material,the vague understandings of logarithmic video amplifiers is existed in engineering applications. Started with the analysis of the concept of logarithmic video amplifier,its technical parameters are discussed mainly. In the end,the principle and method of selecting logarithmic video amplifier are provided.
