无线定位技术广泛应用于各个行业。首先分析了基于TDOA的Chan定位算法，针对Chan算法在测量噪声加大时定位精度下降的问题，将差分演进算法（DE）与Chan算法相结合，提出了一种Chan-DE复合算法，并通过仿真验证了Chan-DE复合算法的有效性。

Wireless positioning technology is widely used in all sectors of society. This paper firstly analyzes the Chan positioning algorithm based on TDOA. To deal with the problem of the positioning precision decreased while measurement noise increased,a composite algorithm named Chan-DE,which combined by Chan algorithm and differential evolution algorithm(DE),has been presented. The validity of the Chan-DE composite algorithm has been verified by simulation.
