一种用于高动态伪卫星的多普勒频率模拟算法

摘要

Pseudolite can stimulate the real satellite signal, according to various factors such as the high dynamic of the carrier. So it can supply the simulation and test environment for the high dynamic receiver. The paper presents a method of simulating Doppler shift. The high dynamic signal can be demodulated by the receiver, which proves the algorithm to be effective and flexible. It can be applied in accurately simulating high dynamic satellite signal.%伪卫星站能够根据载体动态特性等各种因素的影响,模拟产生接收机收到的卫星信号,为高动态接收机的研制开发、测试提供仿真环境.论文提出了载波多普勒模拟算法,应用于卫星的高动态模拟,并用接收机对高动态伪卫星信号进行了解调验证.实测结果表明该算法灵活、有效,可用于精确模拟卫星信号的高动态.
