基于AD9854的BPSK信号源设计

摘要

Researching on GPS jammer, comparing the navigation satellite signal,This paper proposes a design of signal source based on AD9854 and LM3S811 on the basis of jammer design requirements and the basic principle of direct digital frequency synthesizer AD9854. The signal source can produce BPSK signal, which is similar to navigation satellite, used in the ifeld of satellite navigation.%本文对GPS干扰机进行研究，对比导航卫星信号，依据干扰机设计要求和直接数字式频率合成器AD9854的基本原理，提出了一种以AD9854和LM3S811为核心的信号源设计。信号源可产生类似导航卫星发射的BPSK信号，应用于卫星导航领域。
