摘要
针对双站无源定位系统中的时差频差测量问题,从时差频差产生的根本原因入手,研究了利用宽带模糊函数对宽带雷达信号进行时差时间尺度联合估计的快速算法。仿真验证了算法的性能。结果表明,针对宽带信号,该算法有良好的时差时间尺度估计性能。
To solve the measurement problems of time differential of arrival（TDOA） and differential Doppler offset（DFO） in dual-station passive location system,by analyzing the sources of TDOA and DFO firstly,an algorithm of joint fast estimation of TDOA and time-scale is studied based on wide-band-ambiguity-function（WBAF）.The capability of the algorithm is tested by simulation.The results show that the algorithm has fine estimation capability of TDOA and time-scale towards wide-band signals.
