摘　　要：在雷达信号处理中常常要用到延迟时间可调的延迟器件 ,但目前大多数延迟器件都不能满足要求。本文设计了一种新型声光延迟装置。它与以往的延迟器件相比 ,其优点在于延迟时间可连续变化。因此 。The delay device that the time delay is continuously variable is often needed in radar signal processing, but most delay devices don't satisfy the need. Now, this paper presents a new acoustooptic delay device's basic principle and design. Compared with other delay devices, it has an advantage that the time delay is continuously variable. Therefore, this delay device is more suitable for radar target simulation and other high precision signal processing.
