摘　　要：目前针对北斗信号捕获技术研究较多,但缺少系统的分类、总结和性能比较的问题。按照单周期、多周期、辅助捕获三个标准进行研究;同时,分析了捕获算法的硬件实现现状,对国内外捕获研究领域的相关方法进行了系统的整理和综述;对捕获方法进行了性能对比,仿真验证了各自的优劣,指出了北斗系统捕获技术所面临的问题和未来的发展趋势,对捕获领域加强了理论支撑。There is a large number of study on the signal acquisition techniques of BeiDou Navigation Satellite System（BDS）in recent years, however, few focus on the classification, summary and perform- ance comparison. Given this situation, we study the acquisition algorithms based on the following three categorization standards： single-cycle, multi-cycle and auxiliary capture. On the basis of analyzing rele- vant methods in the field at home and abroad, we explore the hardware implementation status of capture algorithms and compare their performance. Simulation results demonstrate the advantages and disadvan- tages respectively. We finally point out the challenges and development trend of BeiDou system signal capture techniques in the future, hoping to provide a theoretical support in this field.
