An Indirect Location Method for Indoor Target Tracking Based on Single Acoustic Vector Sensor
Jiahui Yang, Gao Shesheng, Jiahao Zhang, Gaoge Hu, Guo Li · 2019
The traditional capon spectra estimation is not suitable for extracting direction of arrival (DOA) under impulse noise. In the case of tracking and locating a single target with a single acoustic vector sensor (AVS), the extracted DOA may be incorrect at low signal-to-noise ratio (SNR), especially when there is an interference source near the target. In order to track and locate the target accurately even when the measurement is disturbed by abnormal values, an improved capon spectra estimator is proposed by combining cubature information filtering (CIF) and gating technology. Finally, the effectiveness of proposed method is verified by simulation experiments.
