在对 AD9854的内部结构和外部接口进行深入研究的基础上，运用单片机通过AD9854的并行接口对其内部的可编程寄存器和相关累加器进行控制，经过反复试验探索出了可行的控制方法，实现对AD9854输出脉冲的振荡起始相位的可编程控制。该方法已经用于某型雷达回波信号模拟器中，成功合成了固定目标回波信号。

Based on depth study of internal structure and external interface of AD9854,singlechip is applied to con-trol its interior programmable register and related accumulator through parallel interface of AD9854, to explore fea-sible control method.After reiterative experiment, programmable control is achieved on initial phase of oscillation of output pulse of AS9854.This method has been applied on some radar echo signal simulator,and fulfilled fixed objective echo signal synthesizing.
