光A/D转换

Optical A/D Conversion

高速 A/D转换是雷达、声纳、电子战、飞行器导航及身份识别等国防领域中的关键技术。用超高速光脉冲处理微波信号是实现对超宽带信号 A/D转换的一种新的手段。本文讨论了光子 A/D转换的几种方法 ,并分析了取样脉冲质量对转换精度的影响。

Ultra high speed A/D conversion is a key technique in many military fields,such as radar,sonar,electronic warfare.The A/D conversion of broad band microwave signal using ultra high speed optical pulse is a new method proposed in recent years.In this paper,several methods are discussed and the precision impaired by the optical pulse jitter and pulse width is analyzed.
