A passive locating algorithm based on non-cooperative illuminators using TDOA measurements of double sites

According to the characteristics of non-cooperative illuminators,a passive locating algorithm using TDOA measurements of double sites for planar target is proposed.The modules of locating algorithm and locating error are discussed.The relation between the locating precision and the distance between two sites,and the relation between the precision and the positions of non-cooperative illuminators are primarily calculated.The simulation results of different locating precision curves are also given,indicating that this algorithm performs well in both the location precision and speed.
