The major research works are divided into five sections , including warship bearings - only tracking maneuver research , warship bearings - only tracking research , multi - warships passive data association research , multi - warships passive location research and the engineering implementation of bearings - only passive location systems . the detailed research works are outlined as follows : ( 1 ) a method of evasion factor matrix is presented , which can add the possible patrol zone of targets ( enemy ' s warships ) according to intelligence , and the land and island information provided by electronic chart to the modified gain extended kalman filter , and modifies state equation . it can improve the location precision of the modified gain extended kalman filter 研究內(nèi)容共分五個方面,分別是單艦純方位無源定位機(jī)動研究、單艦純方位無源定位跟蹤研究、多艦無源數(shù)據(jù)關(guān)聯(lián)研究、多艦純方位無源定位研究以及艦艇純方位無源定位系統(tǒng)的工程實(shí)現(xiàn),主要完成了如下的工作: 1提出一種規(guī)避因子矩陣的方法,把根據(jù)情報獲得的目標(biāo)(敵艦艇)可能活動區(qū)域,以及電子海圖提供的陸地島礁信息加入修正增益推廣卡爾曼濾波器中,對目標(biāo)狀態(tài)方程進(jìn)行修正處理,可提高修正增益推廣卡爾曼濾波定位算法的定位精度。
Abstract : starting from the definition of weight , the paper derives the relaton detween the change of the a priori unit weight weight mean error with the result of adjustment . lt is found that the change has influence only on the exploring effect of the posteriori unit weight mean error and gross error and the coordinated factor matrix , and no influence on all other adjustment results 文摘:該文從權(quán)的定義出發(fā),導(dǎo)出了先驗(yàn)單位權(quán)中誤差的變化與平差成果的關(guān)系,發(fā)現(xiàn)其變化僅對驗(yàn)后單位權(quán)中誤差、粗差探測效果和協(xié)因數(shù)陣有影響,對其它平差成果均無影響。
