摘　　要：对导航卫星应用到双站雷达中存在的功率、同步以及干涉等关键问题进行了分析。分析了双站雷达的信噪比的影响因素,得出目标散射面积和允许的最大接收机到目标斜距的关系。分析双站雷达面临的三大同步问题,给出了同步的思路和实现方法。分析了系统的干涉,并提出了解决思路。The three important problems are analyzed, such as power, synchronization and interference in the application of global navigation satellite to bistatic radar. The affect factors of signal to noise ratio are analyzed. The relationship between target＇s RCS and the max distance of receiver to the target is acquired. Three problems of synchronization this bistatic SAR faced are analyzed and the realizing methods and ways are provided. Interference in this system is analyzed and the resolving methods are represented.
