摘要

对北斗卫星作为机会辐射源的可行性进行分析

研究了北斗卫星信号Kasami码的模糊函数。仿真表明:信号有良好的距离与速度分辨力。提出基于到达时间差（TDOA）的T—Rn型被动雷达总体最小二乘TLS定位方法的理论推导

并针对TLS算法的缺点给出递推TLS（RTLS）算法。仿真表明:该算法逼近TLS算法

能够实时更新且节省硬件资源。

Abstract

By taking Beidou Kasami signal as research object

the feasibility of the Beidou signal as an opportunity illuminator of the passive radar is analyzed in the respects of monostatic ambiguity function and bi-static ambiguity function. T-Rntype based on time difference of arrival（ TDOA） is given and location algorithm of total least squares（ TLS） positioning method theory is derived. Base on that

an improved location algorithm

recursive total least squares（ RTLS） algorithm is proposed. Simulation results show that the RTLS algorithm is approximate to the TLS algorithm

it takes up less hardware resources and has real-time update performance.
