Programmable Control on Initial Phase of Oscillation Using AD9854

Abstract:

Based on in depth study of internal structure and external interface of AD9854, applying singlechip to control its interior programmable register and related accumulator through parallel interface of AD9854, to explore feasible control method, after reiterative experiment, achieved programmable control on initial phase of oscillation of output pulse of AD9854. This method had applied on some radar echo signal simulator, fulfilled fixed objective echo signal synthesizing.
