许多无源定位问题中都存在强干扰,可能导致传统定位方法失效。在本研究中,提出了一种混合无源定位方法来解决强干扰。该方法结合了广义互相关和干扰消除来进行到达时间差 (TDOA) 测量,然后采用基于时延的迭代定位方法。该方法应用于使用三个水听器的初步实验。将所提出的方法估计的 TDOA 与粒子滤波方法获得的 TDOA 进行了比较。结果表明,当准确获得 TDOA 时,位置是一致的。此外,所提出的方法在存在强移动干扰源的情况下更能够定位。
Strong interference exists in many passive localization problems and may lead to the inefficacy of traditional localization methods. In this study, a hybrid passive localization method is proposed to address strong interference. This method combines generalized cross-correlation and interference cancellation for time-difference-of-arrival (TDOA) measurement, followed by a time-delay-based iterative localization method. The proposed method is applied to a preliminary experiment using three hydrophones. The TDOAs estimated by the proposed method are compared with those obtained by the particle filtering method. Results show that the positions are in agreement when the TDOAs are accurately obtained. Furthermore, the proposed method is more capable of localization in the presence of a strong moving jamming source.
