卫星导航系统接收机小型化是未来发展的趋势，基于小型导航接收机的无线传感器网络具有新优点的同时也面临新的问题。研究分析了导航系统接收传感器网络所面临的攻击特点，传统无线传感器网络的干扰检测方法难以准确定位干扰和校正位置，提出了基于改进的到达角度定位机制的攻击检测算法确定受到干扰的点，并进行干扰校正；然后基于导航系统抗欺骗干扰原理，提出了单干扰源双曲线定位算法。最后，利用所提算法进行实验，结果表明，攻击检测和校正效率很高，理想条件下干扰源定位效率也较高。

Miniaturization of the satellite navigation receiver is the development trend in the future.The characteristics of attacking for the satellite navigation receiver network are analyzed.Since it is difficult to accu-rately position and correct the interference with the traditional wireless sensor network (WSN)interference de-tection method,an algorithm based on the improved angle of arrival(AOA)positioning mechanism for the attack detection is proposed.And then a hyperbolic positioning algorithm is put forward based on the principle of satel-lite navigation system for deception jamming single interference sources to locate the interference sources.Final-ly,the experiment by using the algorithm is conducted.The result shows that the attack detection and correc-tion efficiency are very high.
