针对非合作外辐射源的特点,提出了一种对二维运动目标的两站时差定位方法,给出了定位的算法模型和定位误差模型,并初步计算了定位精度与两站之间距离、非合作外辐射源位置的关系,给出了各种定位精度曲线仿真结果。仿真结果表明,此定位方法具有较好的定位精度和定位速度。

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 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.
