摘　　要：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, antistealth ability, anti-jamming capability, simple structure and reliable performance. For this reason, it has been gained the attention 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 different 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.
