However, one problem with this multi-source network is that it brings a huge amount of information and leads to considerable computational load. Aiming at the problem, this paper introduces the idea of selecting external illuminators in the multistatic passive radar system. Its essence is to optimize the configuration of multistatic T\/R pairs. Based on this, this paper respectively proposes two multi-source optimization algorithms from the perspective of resolution unit and resolution capability, the Covariance Matrix Fusion Method and Convex Hull Optimization Method, and then uses a Global Navigation Satellite System (GNSS) as an external illuminator to verify the algorithms. The experimental results show that the two optimization methods significantly improve the accuracy of multistatic positioning, and obtain a more reasonable use of system resources. To evaluate the algorithm performance under large number of transmitting\/receiving stations, further simulation was conducted, in which a combination of the two algorithms were applied and the combined algorithm has shown its effectiveness in minimize the computational load and retain the target localization precision at the same time.<\/jats:p>","DOI":"10.3390\/rs13040707","type":"journal-article","created":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T05:52:49Z","timestamp":1613368369000},"page":"707","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Target Localization Based on Bistatic T\/R Pair Selection in GNSS-Based Multistatic Radar System"],"prefix":"10.3390","volume":"13","author":[{"given":"Yu\u2019e","family":"Shao","sequence":"first","affiliation":[{"name":"The National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Ma","sequence":"additional","affiliation":[{"name":"The National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shenghua","family":"Zhou","sequence":"additional","affiliation":[{"name":"The National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7892-5762","authenticated-orcid":false,"given":"Xue","family":"Wang","sequence":"additional","affiliation":[{"name":"The National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"},{"name":"The Institute of Information Sensing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michail","family":"Antoniou","sequence":"additional","affiliation":[{"name":"The School of Electronic, Electrical and Systems Engineering, University of Birmingham, Birmingham B15 2TT, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongwei","family":"Liu","sequence":"additional","affiliation":[{"name":"The National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"},{"name":"The Institute of Information Sensing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,15]]},"reference":[{"key":"ref_1","unstructured":"Liu, J.Y.
