摘　　要：传统GPS干扰试验缺乏量化评估干扰效能的有效手段。针对这一问题,对GPS接收机定位处理算法开展了研究,在分析影响定位精度的主要因素之后,将精度衰减因子(DOP)算法设定为研究重点。经过深入分析,选出了最适用于干扰试验效能评估的DOP算法。在验证试验中尝试运用了该算法,对数据的分析结果表明该方法可行,可以用该算法评估GPS定位精度的恶化程度,量化干扰效能。There is a lack of effective means to quantitativly evaluate the GPS jamming efficiency in traditional GPS jamming tests. To solve this problem, the algorithms for GPS receiver positioning processing are researched. After analyzing the major factors affecting the positional precision, DOP algorithms are focused on. Thorough analysis, the most applicable DOP algorithm for effectiveness evaluation of jamming test is selected. This algorithm is used in verification test. Data analysis result proves that this method is feasible, which can be used to evaluate the deterioration degree of GPS positional precision,and could quantize the jamming efficiency.
