摘　　要：由于受到延迟时间固定不变或只能离散变化的限制 ,许多雷达目标模拟器不能模拟连续运动目标的变化。为此 ,设计了一种新型的声光延迟系统 ,并对该系统的性能作了分析。与其它延迟系统相比 ,本系统的优点在于延迟时间可连续变化 ,延迟总时间可满足信号处理的要求。因此 ,它可以方便地应用于运动雷达目标模拟和其它信号的处理。With limited to fixed delays or discrete delays, many radar target simulatiors can't simulate continuous target motion So, a new acoustooptic delay system is designed and its properties is analyzed in this paper Compared with other delay systems, it has an advantage that the time delay is continuously variable, so that it can satisfy the need of signal delay processing Therefore, this delay system is more suitable for radar target simulation and other signal processing
