基于民用移动通信信号的无源雷达系统具有隐蔽性好、反隐身能力及抗干扰能力强、系统简单可靠等优点，近年来受到各国的重视，得到了较快的发展。针对基于民用移动通信信号的无源定位系统中Chan氏算法和Taylor级数算法的实现过程展开分析研究，并在不同的基站配置下，与其相应的定位精度卡拉美罗下限进行了比较，发现当测量误差的均方差较小时，利用Chan氏算法和Taylor级数算法均可以逼近卡拉美罗下限。%The passive radar based on civil communication signals has many advantages,such as good invisibility,anti⁃stealth ability,anti⁃jamming capability,simple structure and reliable performance. For this reason,it has been gained the atten⁃tion of various country,and has a rapid development. The realization process of Chan algorithms and Taylor series algorithms in passive location system based on civil mobile communication signals is analyzed. Compared with the Cramer⁃Rao Bound in differ⁃ent base station configuration,it is found that when the mean square error of the measure error is small,location accuracy can approach to the Cramer⁃Rao Bound.
