| Abstract: | 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. |
