Digital receiver input SINR has a great impact on acquisition performance. In this paper, theoretical analysis and a large number of simulation are given to analyze the impact of quantization bits on the relative acquisition peak and SINR of navigation signals, and under a given anti-＇jamming indicator, the required minimum and maximum quantization bits of satellite navigation and anti-jamming system are given in the experiment. A reasonable choice of quantization as a theoretical basis be provided to the navigation anti-jamming system.%数字接收机输入端的信噪比对其捕获性能具有较大的影响，文中通过理论和大量实验反正分析了量化位数对导航信号相对捕获峰值及信噪比的影响。并分析了在给定抗干扰指标下卫星导航抗干扰系统所需的最小及最多量化位数．为实现导航抗干扰系统时合理选择量化位数提供了理论依据。
