摘　　要：鉴于卫星技术的快速发展和广泛应用,利用卫星无源定位系统以适应当今高科技战场对电子战武器的隐蔽攻击的需求已经成为一个重要的发展方向,而单星无源定位系统具有成本低、灵活性好等优点,成为研究的热点。研究单星频差无源定位原理和定位方法,针对定位模糊问题提出了解决方案,分析了影响定位精度的因素并推导了定位的理论误差和圆概率误差。For the rapid development and abroad application of satellite technology, it becomes an important development direction to adapt the demand of concealment attack of current high-tech battlefield to EW weapon by using satellite passive location, and the merits such as low cost and good agility of single satellite passive location system become hot points of research. This paper studies the principle and method of single satellite frequency difference passive location, puts forward the solution project aiming at the problem of location ambiguty,analyzes the factors influencing location precision and deduces the principle error and circular error probable （CEP） of location.
