由远场TDOA或FDOA确定DOA的新方法
A Novel Method for Determining DOA from Far-Field TDOA or FDOA
摘要：
通常使用到达时间差（TDOA）测量、到达频率差（FDOA）测量、到达波达方向（DOA）测量或所有这些的组合来执行被动源定位。对于远场中的源，由于在远场近似中出现的简化，可以从TDOA和FDOA测量中提取DOA。本文提出了这种关系式和相应的DOA估计方法。利用TDOA和FDOA测量来计算信号DOA仅需要线性求解，这使得相应的源定位技术非常有效。此外，该方法提供了接收器测量的固有去噪，因为它们被投影到接收器差分矩阵的范围上。
英文摘要：
Passive source localization is often performed using time difference of arrival (TDOA) measurements, frequency difference of arrival (FDOA) measurements, direction of arrival (DOA) measurements, or a combination of all of these. For a source in the far-field, DOA can be extracted from the TDOA and FDOA measurements due to simplifications that arise in the far-field approximation. This paper presents this relationship and the corresponding DOA estimation method. Utilizing TDOA and FDOA measurements for computation of signal DOA requires only a linear solve, which makes the corresponding source localization technique very efficient. Additionally, the method provides an inherent de-noising of receiver measurements, since they are being projected onto the range of the receiver differencing matrix.
