In order to overcome the problem of particle decay in particle filtering, UT is adopted to select a group of sigma points with different weights to make them close to the posterior probability density of the state. Since the \u03b1 stable distribution does not have finite covariance, the Fractional Lower Order Moment (FLOM) matrix of the received array data is employed to replace the covariance matrix to formulate a MUSIC spatial spectra in the MeMBer filter. Further exponential weighting is used to enhance the weight of particles at high likelihood area and obtain a better resampling. Compared with the PASTD algorithm and the MeMBer DOA filter algorithm, the simulation results show that the proposed algorithm can more effectively solve the issue that the DOA and number of target are time-varying. In addition, we present the Sequential Monte Carlo (SMC) implementation of the UT-MeMBer algorithm.<\/jats:p>","DOI":"10.3390\/s19184031","type":"journal-article","created":{"date-parts":[[2019,9,19]],"date-time":"2019-09-19T03:40:06Z","timestamp":1568864406000},"page":"4031","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["DOA Tracking Based on Unscented Transform Multi-Bernoulli Filter in Impulse Noise Environment"],"prefix":"10.3390","volume":"19","author":[{"given":"Sun-yong","family":"Wu","sequence":"first","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541004, China"},{"name":"Guangxi Information Science Experiment Center, Guilin 541004, China"}]},{"given":"Jun","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Xu-dong","family":"Dong","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Qiu-tiao","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Ru-hua","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Mathematics and Computing Science, Guilin University of Electronic Technology, Guilin 541004, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1109\/79.526899","article-title":"Two decades of array signal processing research","volume":"13","author":"Kim","year":"1996","journal-title":"IEEE Signal Process.
