摘　　要：复杂的信号应用环境和信号处理过程对高性能精密全球卫星导航(Global Navigation Satellite System,GNSS)信号性能评估产生一定影响。介绍了一种基于时分数据调制(Time Divide Data Modulate,TDDM)的二进制偏移载波调制(Binary Offset Carrier,BOC)的无周期长码现代化GNSS信号,提出了一种基于模块化软件的GNSS信号性能测试评估技术,对该现代化GNSS信号进行基带处理和抗干扰性能的评估。计算机仿真和硬件测试结果的对比验证了所提方法的可行性和有效性。The performance evaluation of high performance exact Global Navigation Satellite System （ GNSS） signals will be influ-enced by the complicated application environment and the signal process. This paper introduces a non-periodic code Binary Offset Car-rier （ BOC） modulation modern GNSS signal based on TDDM,proposes a performance test and evaluation technology of GNSS signals based on self-compiled software to evaluate the baseband processing and anti-jamming performance of modern GNSS signals. The con-trast between computer simulation and hardware test proves the feasibility and availability of the proposed method.
