| Abstract: | Passive location system detects target without send electromagnetic wave,it has good concealment performance and good graces by force.Aimed at fixed multiple observer passive location based on TDOA and FDOA information,a IMM filter algorithm of location and tracking moving-target is presented.Firstly the principle of location is expatiation,and then the process of IMM algorithm is particular presentation,lastly,it is confirmed that the multiple-model algorithm is legitimacy and feasible through computer sim... |
