摘　　要：针对三机三维布阵优化问题,以精度因子为目标函数,以阵面旋转为切入点,采用建模仿真方法,分析了阵面旋转效应对三机时差定位、频差定位及时频差定位精度的影响,直观地揭示了不同定位体制下的布阵优化规律。这些规律在下步工作中可作为先验知识,与粒子群、模拟退火、遗传算法等最优化方法相结合,更精细地研究三机三维布阵优化问题。Aiming at 3-aircraft 3-dimensional sensor placement optimization, the accuracy factor was taken as objective function and sensor placement was studied from the pointview of the placement plane rotation. And then, based on the modeling and simulation strategy, the placement plane rotation effect was analyzed on the location precision of time difference of arrival （TDOA） localization, frequency difference of arrival （FDOA） localization and hybrid TDOA/FDOA localization, which revealed the rules of sensor placement optimization under different types of localization systems. These rules could be very useful to three-dimensional sensor placement optimization when these were associated with particle swarm algorithm, simulated annealing, genetic algorithm and so on.
