Accession number: 20150400441250 Title: Algorithm of asynchronous sensors bias estimation in networked targeting Authors: Yong, Xiaoju1 ; Fang, Yangwang1; Zhang, Dengfu1; Diao, Xinghua1 Author affiliation: 1 Aeronautics and Astronautics Engineering College, Air Force Engineering University, Xi'an, China Corresponding author: Yong, Xiaoju Source title: Beijing Hangkong Hangtian Daxue Xuebao/Journal of Beijing University of Aeronautics and Astronautics Abbreviated source title: Beijing Hangkong Hangtian Daxue Xuebao Volume: 40 Issue: 12 Issue date: December 1, 2014 Publication year: 2014 Pages: 1707-1712 Language: Chinese ISSN: 10015965 CODEN: BHHDE8 Document type: Journal article (JA) Publisher: Beijing University of Aeronautics and Astronautics (BUAA) Abstract: Aimed at the problem that the algorithm of asynchronous sensors bias estimation cannot adapt to the maneuver targets, a novel algorithm based on the interpolation was researched. Firstly, the measurement was changed into synchronization data by using the time registration method. Then, the pseudo measurement equation could be obtained according to the time registration results. Be different from other algorithms of which the pseudo measurement, independent of target state, is obtained by getting a adding coefficient according to the target state vector and time of arrival (TOA), the depseudo measurement deigned has no relationship to the target state vector. Moreover, the derivation of the pseudo measurement according to the time registration results is also independent of the movement of target. So, the problem of asynchronous sensors bias estimation with maneuver targets can be solved by the algorithm proposed. The results of simulation show that the sensor bias could be exactly estimated when the target takes a snake maneuver.
