摘要
利用两种方法,即模糊函数和四阶累积量模糊函数对目标的两个主要参量TDOA(time-delay of arrival)和FDOA(frequency-delay of arrival)进行理论上精确的推导和实际应用中在工程上的估计,并且指出了两种方法在理论与实际应用中所得到的两种几乎截然不同的结果,并对其加以详细的分析,阐明了这种矛盾的根源之所在,并由给出的仿真结果对上述结论加以说明。
Two methods,two ambiguity functions based on second-order and fourth-order statistics,are used to estimate FDOA（frequency-delay of arrival） and TDOA（time-delay of arrival） accurately in engineering and theory computation.While the results is completely different,of which some analysis is illuminated in details and the possibility is reasoned.The simulation results are explained after two sides analyzing at last.
