A six degrees of freedom swing platform fixed with a MiniRadaScan is used to simulate the loss of observations. The state transition model based on the historical observation data fit prediction is designed because the existing state estimation method can only use the system model prediction while the observation is missing. An observation data sliding window width adaptive adjustment strategy is proposed that can improve the fitting accuracy of the state transition model. To solve the problem where the weight value of the Gaussian components of the Gaussian mixture filter is not changed in the time update stage while the observation is missing, an adaptive adjustment strategy for the weight is proposed based on the Chapman\u2010Kolmogorov equation, which can improve the estimation precision under the conditions of the missing observation. The simulation test demonstrates the proposed accuracy and real\u2010time performance of the proposed algorithm.<\/jats:p>","DOI":"10.1155\/2018\/5327637","type":"journal-article","created":{"date-parts":[[2018,12,2]],"date-time":"2018-12-02T23:33:37Z","timestamp":1543793617000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A New State Estimation Method with Radar Measurement Missing"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1187-0135","authenticated-orcid":false,"given":"Hongjian","family":"Wang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9412-5282","authenticated-orcid":false,"given":"Cun","family":"Li","sequence":"additional","affiliation":[]},{"given":"Ying","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Qing","family":"Li","sequence":"additional","affiliation":[]},{"given":"Xicheng","family":"Ban","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2018,12,2]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2004.834121"},{"key":"e_1_2_10_2_2","doi-asserted-by":"crossref","unstructured":"LiuX.andGoldsmithA.
