In h paper, he MTT problem ued for emang he poon of mulple arge when a -D radar employed o gaher meauremen. To do o, he Jon Probabl Daa Aoaon Fler (JPDAF approah appled o rang he poon of mulple arge. To haraerze he moon of eah arge, wo model are ued. Fr, a mple near onan veloy model ondered and hen o enhane he rang performane, peally, when arge mae maneuverng movemen a varable veloy model propoed. In addon, a ombned model alo propoed o mgae he maneuverng movemen beer. Th new model gve an advanage o explore he movemen of he maneuverng obe whh ommon n many rang problem. Smulaon reul how he uperory of he new moon model and effe n he rang performane of mulple arge. KEYWORDS Mulple arge rang, JPDAF algorhm, daa aoaon, maneuverng movemen. ITRODUCTIO The problem of emang he poon of a arge n phyal envronmen an mporan problem n he mlary feld. Indeed, beaue of he nrn error embedded n he daa olleed by meauremen enor, here range and bearng fnder, ome operaon hould be ondued on he rude daa o reah more aurae nowledge abou he poon of a arge. owaday, varou algorhm are propoed o modfy he auray of loalzaon algorhm. In he feld of arge rang, he Kalman fler approah [] play a gnfan role. Th approah ue a uggeed model derbng he arge movemen and he meauremen olleed by a -D radar and, hen, provde an aurae emaon of he arge poon. ow, he Kalman fler grealy ued n many rang problem []. Alhough h fler ha provded a general raegy o olve loalzaon problem, uffer from ome weanee. The mo gnfan problem of he Kalman mehod weane o he ae emaon of many real yem n he preene of evere nonlneare. Aually, n general nonlnear yem, he poeror probably deny funon of ae gven meauremen anno be preened by a Gauan deny funon and, herefore, he Kalman mehod may reul n unafaory repone. Moreover, he Kalman fler very enve o he nal ondon of ae. Aordngly, Kalman baed mehod do no provde aurae reul n many ommon global loalzaon problem.

Alhough h problem appear mlar o he ommon loalzaon algorhm n whh he dynamal model of he arge nown, he radonal approahe anno be ued beaue he radar doe no have ae o he nernal enor daa of eah arge ued n loalzaon algorhm o pred he fuure poon of he arge. Moreover, ung he parle fler o emae he poon of all arge, nown a ombned ae pae, no raable beaue he omplexy of h approah grow exponenally wh he number of obe beng raed. To reolve he problem of he la of nernal enor daa, varou moon model have been propoed. The mple model propoed he near onan veloy model. Th model ha been grealy ued n many rang applaon uh a arraf rang [], people rang [] and ome oher arge rang applaon [3]. Bede h model, ome oher ruure have been propoed uable n ome oher peal applaon. ear onan aeleraon model a modfed veron of he prevou model whh an be appled o rang maneuverng obe [4]. Alo, nerave mulple model (IMM fler repreen anoher ool o ra he movemen of hghly maneuverng obe where he former propoed approahe are no relable [5]. Reenly, many raege have been alo propoed n he leraure o addre he dffule aoaed wh mularge rang. The ey dea of he leraure o emae eah obe poon eparaely. To do o, he meauremen hould be agned o eah arge. Therefore, daa aoaon ha been nrodued o relae eah arge o aoaed meauremen. By ombnng daa aoaon onep wh flerng and ae emaon algorhm, he mulple arge rang ue an be deal wh eaer han applyng ae emaon proedure o he ombned ae pae model. Among he varou mehod, Jon Probabl Daa Aoaon Fler (JPDAF algorhm aen no aoun a one of he mo arave approahe. The radonal JPDAF [6] ue Exended Kalman Flerng (EKF on wh he daa aoaon o emae ae of mulple obe. However, he performane of he algorhm degrade a he nonlneare beome more evere. To enhane he performane of he JPDAF agan he evere nonlneary of dynamal and enor model, reenly, raege have been propoed o ombne he JPDAF wh parle ehnque nown a Mone Carlo JPDAF, o aommodae general nonlnear and non-gauan model [7]. The newer veron of he above-menoned algorhm ue an approah named a of gang o redue he ompuaonal o whh one of he mo erou problem n onlne rang algorhm [7]. Bede he Mone Carlo JPDAF algorhm, ome oher mehod have been propoed n he leraure. In [7], a omprehenve urvey ha been preened on he mo well-nown algorhm applable n he feld of mulple arge rang. In h paper, he Mone Carlo JPDAF algorhm ued for he mulple arge rang problem. A a modfaon o he reen leraure, dfferen moon model are eed o evaluae he performane of rang. Bede he radonal near onan veloy model, we wll e he effeny of he oher wo model a well n he paper. Fr, a varable veloy model ued o haraerze he movemen of arge. Then, we propoe a ombned approah n whh he moon model a lnear ombnaon of onan and varable veloy model. In addon, a mple algorhm repreened o deermne he wegh agned o eah moon model. I hown ha ome nformaon of he JPDAF algorhm an be ued o deermne he aforemenoned faor. The goal, here, o ufy he effeny of he JPDAF algorhm ung ombned model ompared wh eah ndvdual model. The re of h paper organzed a follow. Seon II derbe he Mone Carlo JPDAF algorhm for mulple arge rang. The JPDAF for mulple arge rang he op of eon III. In h eon, we wll preen how he moon of arge n a real envronmen an be derbed. To do o, near onan veloy and aeleraon model are nrodued o derbe he movemen of moble arge. Then, wll be hown how daa reeved from a -D radar an be ued for rang movng obe. In eon IV, varou mulaon reul are preened o uppor he performane of he algorhm. In h eon, he maneuverng movemen of he arge alo ondered. The reul ealy approve he uable performane of he JPDAF algorhm n rang he moon of moble arge n he mulaed envronmen.
